## Algebra 1: Common Core (15th Edition)

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: $\frac{3-0}{3-0}=\frac{3}{3}=1$
