Answer

The line rises from left to right. So, the slope is positive. Slope $m=\frac{2}{3}$.

Work Step by Step

The line rises from left to right. So, the slope is positive. Let $(x_{1},y_{1})=(-3,-1)$ and $(x_{2},y_{2})=(3,3)$ Slope $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{3-(-1)}{3-(-3)}=\frac{4}{6}=\frac{2}{3}$.
