Answer
Refer to the graph below.
Work Step by Step
The slope is rise over run.
Thus, the given line has a rise of $1$ and a run of $2$.
To graph the line, perform the following steps:
(1) Plot the y-intercept $(0, 0)$.
(2) From $(0, 0)$, move 1 unit up (the rise) and 2 units to the right (the run) to reach $(2, 1)$. Plot $(2, 1)$.
(3) The slope $\frac{1}{2}$ is equivalent to $\frac{-1}{-2}$, so the rise can be $-1$ and the run $-2$.
From $(0, 0)$, move 1 unit down and 2 units to the left to reach $(-2, -1)$. Plot $(-2, -1)$.
(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.
