What is a positive slope?
A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
How do you find the positive slope?
The positive slope for a line can be calculated using the formulae m = (y2 – y1)/(x2 – x1) = Tanθ = f'(x) = dy/dx. The positive slope signifies that the two quantities represented along the two axes of the coordinate system increase or decrease at the same time.
What is a positive slope and a 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 a positive slope in a graph?
A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
What does negative slope mean?
Visually, a line has negative slope if it goes down and right (or up and left). Mathematically, this means that as x increases, y decreases.
What is an example of a negative slope?
For example, as the number of people that quit smoking (x) increases, the number of people contracting lung cancer (y) decreases. A graph of this relationship has a negative slope.
How can you tell if a slope is positive or negative?
If the line is sloping upward from left to right, so the slope is positive (+). If the line is sloping downward from left to right, so the slope is negative (-). In our pizza example, a positive slope tells us that as the number of toppings we order (x) increases, the total cost of the pizza (y) also increases.
What does a negative slope look like?
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 makes a slope negative?
A slope can be negative when the two variables are inversely related to one another, as one increases, the other decreases. You can find the slope of a line by looking at a graph, looking at an equation, or using the slope formula.
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.

How is a slope negative or positive?
If the line is sloping upward from left to right, so the slope is positive (+). If the line is sloping downward from left to right, so the slope is negative (-).

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.
Is a 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 know if a slope is negative?
The graph of a negative slope moves downwards from left to right. When looking at a graph on an xy coordinate plane, as x increases, y decreases, making it a negative slope.
What is a 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.
Which line has a positive slope?
The slope of a line is considered to be a positive slope line if the right side of the line is higher, or, has a greater vertical value than the left side of the line. The steepness of the line in the graph can vary as long as it does not go completely vertical in which case the line has an undefined slope.
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.

How do you tell if a slope is negative or positive on a graph?
If the line is sloping upward from left to right, so the slope is positive (+). If the line is sloping downward from left to right, so the slope is negative (-). In our pizza example, a positive slope tells us that as the number of toppings we order (x) increases, the total cost of the pizza (y) also increases.

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.
