Answer

The slope is not defined because the line is vertical. There is no $y$-intercept since the line does not pass through the $y$-axis. Refer to the graph below.

Work Step by Step

The slope of the line can be obtained by looking at the coefficient of $x$ in the slope-intercept form. $x=-2$ is a vertical line so the slope is not defined. There is no $y$-intercept because the line does not pass through the $y$-axis. All points on the line $x=-2$ have a $y$-coordinate of $-2$. Refer to the graph above.
