## Intermediate Algebra for College Students (7th Edition)

We know that by the Slope Formula: if $P_1(x_1,y_1)$ and $P_2(x_2,y_2)$ are on a line, then the slope is: $m=\frac{y_2-y_1}{x_2-x_1}$. Hence here: $m=\frac{-3-3}{7-(-2)}=\frac{-6}{9}=\frac{-2}{3}.$ The slope is negative thus the line rises from right to left.
