Answer

Refer to the graph below.
1514727601

Work Step by Step

The slope is rise over run. The slope is$-3$, so the rise is $-3$ and the run is $1$. To graph the line, perform the following steps: (1) Plot the y-intercept $(0, 2)$. (2) From $(0, 2)$, move 3 units down (the rise) and 1 unit to the right (the run) to reach $(1, -1)$. Plot $(1, -1)$. (3) The slope $-3$ is equivalent to $\frac{3}{-1}$, so the rise can be $3$ and the run is $-1$. From $(0, 2)$, move 3 units up and 1 unit to the left to reach $(-1, 5)$. Plot $(-1, 5)$. (4) Connect the three points using a line to complete the graph. Refer to the attached image in the answer part above for the graph.
