What is an example of a positive slope?
An example of a positive slope of a line is one where the right side of the line is higher than the left side. Another example is when looking at a mountain where the low ground is on the left and the peak of the mountain is on the right. The slope, or side of the mountain would be positive.
What is positive and negative slope?
A positive slope means y increases as x increases (visually, the line moves up as you go from left to right). A negative slope means y decreases as x increases (visually, the line moves down as you go from left to right). A zero slope means that y is constant and does not change as x changes.
What is negative slope?
Negative slope refers to the slope of a line that is sloping downwards as we are moving from left to right. The angle made by a line with a negative slope is an obtuse angle with respect to the positive x-axis. A negative slope gives an inverse relationship between two variables.
How do you determine if a slope is positive or negative?
0:221:46How to Determine if a Slope Is Positive, Negative, Undefined, Zero …YouTubeStart of suggested clipEnd of suggested clipThen this is going to be a negative slope line so positive slope goes up negative slope goes down.MoreThen this is going to be a negative slope line so positive slope goes up negative slope goes down. Now a line that has a zero slope is going to be a horizontal.
How do you draw a positive slope?

What is a positive slope equation?
In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. Lines with a positive gradient slope upwards, from left to right.
What is a negative slope on a graph?
A line with a negative slope is a line that is trending downward from left to right. In other words, the line's rise to run ratio is a negative value.
What is a positive graph?
A positive linear graph is a graph where all the y-values are positive. The following image contains an example of a positive linear graph: A positive linear graph has positive y-values. Even though this function is not going up, it is still a positive linear graph because its y-values are all positive.
Is a positive sloping curve?
A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y also decreases. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
What is the graph of a positive slope?
If a line has a positive slope (i.e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.
Which line has a negative slope?
Definition of Negative Slope Lines A line with a negative slope is a line that is trending downward from left to right. In other words, the line's rise to run ratio is a negative value.

What is a positive y-intercept?
A positive y-intercept means the line crosses the y-axis above the origin, while a negative y-intercept means that the line crosses below the origin. Simply by changing the values of m and b, we can define any straight line. That's how powerful and versatile the slope intercept formula is.
What is a positive curve?
Curves with a Positive Slope Both graphs at the right show curves sloping upward from left to right. As with upward sloping straight lines, we can say that generally the slope of the curve is positive. While the slope will differ at each point on the curve, it will always be positive.
How do you know if a graph is positive or negative?
Positive or Negative A function is positive when the y values are greater than 0 and negative when the y values are less than zero. Here's the graph of a function: This graph is positive when x is less than 2 and negative when x is greater than 2.
How do you graph a positive slope?
Example 1: Graphing a Positive Slope
- Plot the 1st point. ( 0,-2)
- Count the rise. Since the rise is positive 2, I counted up 2.
- Count the run. Since the run is positive 3, I counted to the right 3.
- Plot your second point. …
- Repeat the process to plot a third point.
- Draw a straight line through your points.
What is a negative and positive?
Whole numbers, figures that do not have fractions or decimals, are also called integers. They can have one of two values: positive or negative. Positive integers have values greater than zero. Negative integers have values less than zero. Zero is neither positive nor negative.
What does negative intercept mean?
The negative intercept tells you where the linear model predicts revenue (y) would be when subs (x) is 0. Your question appears to be prompted by confusion about the fact that in your fitted model, E(Y|x=0)≠0, even though logically, you would expect no revenue then.
Which way does a positive slope go?
Note that when a line has a positive slope it goes up left to right. Note that when a line has a negative slope it goes down left to right. Note that when a line is horizontal the slope is 0. Note that when the line is vertical the slope is undefined.
What does a positive graph look like?
Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises. We will learn in other sections that “price” and “quantity supplied” have a positive relationship; that is, firms will supply more when the price is higher.
How do you write a negative slope?

How do you know if an answer is positive or negative?
When multiplying (or dividing) two numbers with the same signs, the resulting answer is positive. If one is positive and the other negative, the answer will be negative.
What does a positive intercept mean?
A positive y-intercept means the line crosses the y-axis above the origin, while a negative y-intercept means that the line crosses below the origin.
How do you interpret a slope?
If the slope of the line is positive, then there is a positive linear relationship, i.e., as one increases, the other increases. If the slope is negative, then there is a negative linear relationship, i.e., as one increases the other variable decreases.
How do you make a line with a positive slope?
Examples of Positive Slope
- The given slope of the line is m = 3/4, and the point is (x1,y1) ( x 1 , y 1 ) = (1, 2).
- The equation of a line with a positive slope m and passing through the point (x1,y1) ( x 1 , y 1 ) is:
- y−y1=m(x−x1)
What is rise of a negative slope?
If the slope is negative, then the rise and the run have to be opposites of each other, one has to be positive and one has to be negative. In other words, you will be going up and to the left OR down and to the right.
What is the negative and positive rule for math?
If both numbers are positive, the result is positive. If both numbers are negative, the result is positive. (Basically, the two negative values cancel each other out). If one number is positive and the other is negative, the result is negative.
What is negative intercept?
The negative intercept tells you where the linear model predicts revenue (y) would be when subs (x) is 0. Your question appears to be prompted by confusion about the fact that in your fitted model, E(Y|x=0)≠0, even though logically, you would expect no revenue then.
What if the slope intercept is negative?
If the slope is negative, then the rise and the run have to be opposites of each other, one has to be positive and one has to be negative. In other words, you will be going up and to the left OR down and to the right.
