#### Answer

Refer to the graph below.

#### 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 $(0, 4)$. (2) From $(0, 4)$, move 3 units up (the rise) and 1 unit to the right (the run) to reach $(1, 7)$. Plot $(1, 7)$. (3) The slope $3$ is equivalent to $\frac{-3}{-1}$, so the rise can be $-3$ and the run is $-1$. From $(0, 4)$, move 3 units down and 1 unit to the left to reach $(-1, 1)$. Plot $(-1, 1)$. (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.
