#### Work Step by Step

RECALL: (1) The graph of the equation $x=h$ is a vertical line whose x-intercept is $h$. (2) The graph of the equation $y=k$ or $f(x) =k$ is a horizontal line whose y-intercept is $k$. The given equation is similar to the form in (2) above. Thus, its graph is a horizontal line whose y-intercept is $3$. (refer to the attached image in the answer part above for the graph)
