Slope 3 Of course if your equation is in slope-intercept form the slope is the value next to x. A Slope can be referred to as a piece of ground that has a specific slant which is also called a Grade. For this equation y 3x 2 is in slope intercept form.
Slope direction of a line.
We calculate terrain grade in the same way we calculate the slope of a line. If your equation is not in slope-intercept form you can solve for y and then the slope will be the number next to x. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points rise over run. Determine which trig function to use.
