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

Recall, the equation for point slope form is the following: $y- y_{1}=m(x - x_{1})$, where $(x_{1} , y_{1})$ is a point on the line and m is the slope of the line. Thus, we know that (-2,1) must be a point on the line and that the slope is -3. Thus, we can graph the line (the graph is attached).
