x-intercept: none y-intercept: $(0, -9)$
RECALL: (1) The graph of the equation $y=k$ where $k$ is a real number is a horizontal line. (2) The y-intercept of the horizontal line $y=k$ is $(0, k)$. (3) A horizontal line has a y-intercept but no x-intercept (except y=0, which has infinite x-intercepts). The graph of the given equation is a horizontal line whose y-intercept is $(0, -9)$. The graph has no x-intercept.
