M 7 5 3 1 1 2. Slope is defined as rise over run with rise indicating vertical distance between two points and run indicating the horizontal distance between two pointsStep 2 Pick two points on the line and label their coordinates. You can also use this method if you are given two points on the line without having the line graphed in front of you.
To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
These can be any points the line runs through. Find the y-intercept b. This is because it is the change in the y y -coordinates divided by the corresponding change in the x x -coordinates between two distinct points on the line. The slope of a line in the two-dimensional Cartesian coordinate plane is usually represented by the letter m m and it is sometimes called underline the rate of change between two points.
