$x$-intercept: $(-3, 0)$ no $y$-intercept Refer to the graph below.
Work Step by Step
Recall: The graph of a line in the form $x=h$ is a vertical line whose $x$-intercept is $(h, 0)$. The line has no $y$-intercept unless $x=0$. Thus, the $x$-intercept of the graph of $x=-3$ is at $(-3, 0)$. The graph has no $y-$intercept.
