How do you know if it’s a negative slope?
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.
How do you know if an equation has 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.
What makes a slope negative?
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
How do you know if an equation is positive or negative?
Once you have the numerical answer, then you can apply a very simple rule to determine the sign of the answer:
- When the signs of the two numbers are the same, the answer will be positive.
- When the signs of the two numbers are different, the answer will be negative.
What’s a positive slope?
Positive slope refers to the slope of a line that is inclined upwards as we are moving from left to right. The angle made by a line with a positive slope is an acute angle with respect to the positive x-axis. A positive slope gives a direct proportional relationship between two variables.

What defines 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 tell if a slope is positive or negative or zero or undefined?

What does a positive slope mean?
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 is negative slope and positive 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.
How do you tell if a slope is positive negative zero or undefined?
Positive slope means the graph rises or goes uphill. Negative slope means the graph falls or goes downhill. Zero slope means the line is flat or horizontal. Undefined slope means the line is vertical.

How do you know if a slope is positive negative zero or undefined?
Positive slope means the graph rises or goes uphill. Negative slope means the graph falls or goes downhill. Zero slope means the line is flat or horizontal. Undefined slope means the line is vertical.
Which has 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 also decreases. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
How do you tell if the slope of a tangent line is positive or negative?
If a tangent has a positive slope the graph is increasing around the point of tangency. If a tangent has a negative slope the graph is decreasing around the point of tangency. If a tangent is horizontal the graph is often, but not always, at a peak or trough at the point of tangency.
How do you identify the slope?

What is 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.
What are the difference between positive and negative slope?
A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.
What does a positive slope show?
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.
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 the difference between negative and positive slope?
Slopes can be positive or negative. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.
What is positive slope example?
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.
