Answer
A. 4
B. 0
C. -4
Work Step by Step
The slope is calculated by dividing the change in y by the change in x.
A. $\frac{y_2-y_1}{x_2-x_1}=\frac{50-10}{12-2}=\frac{40}{10}=4$
B. $\frac{y_2-y_1}{x_2-x_1}=\frac{50-50}{16-12}=\frac{0}{4}=0$
C. $\frac{y_2-y_1}{x_2-x_1}=\frac{10-50}{26-16}=\frac{-40}{10}=-4$
