Work Step by Step

The equation for slope is: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$. This means we take the y value of the second point and subtract it by the y value of the first point, and then we divide this by the x value of the second point minus the x value of the first point. Thus, we obtain: $\frac{3-(-1)}{2-0}=\frac{4}{2}=2$
