Y 2 y 1. The slope is calculated by counting the rise and then counting the run. The coefficients are m and b.
You cant divide by zero so a straight up and down vertical lines Slope is undefined.
Slope is given by the equation ymxb but you mistakenly identified b in this equation as the slope. Enter any integer decimal or fraction. This is also known as change in y over change in x or rise over run. Slope m change in y change in x y y 1 x x 1.
