$x$-intercept: $(4, 0)$ 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 intercept of the graph of $x=4$ is at $(4, 0)$. The graph has no $y-$intercept.
