Answer
Refer to the graph below.
Work Step by Step
The graph of an equation of the form $y=k$ is a horizontal line whose y-intercept is $0, k)$.
Each point on the line has a y-coordinate of $k$.
Thus, the graph of $y=1$ is a vertical line whose y-intercept is $(0, 1)$.
Each point on the line has a y-coordinate of $1$.
This, means that the following points are all on the line:
$(-2, 1)$, $(0, 1)$, and $(2, 1)$
Plot the three points listed above then connect them using a line to complete the
graph. (refer to the attached image in the answer part above for the graph)
