Answer
slope = 0
y-intercept = 4
Refer to the attached image for the graph.
Work Step by Step
RECALL:
The graph of $y=k$ is a horizontal line whose slope is zero., and contains all the points (x, k) where x is a real number.
Thus, the graph of $y=4$ is a horizontal line with a slope of zero and contains all the points (x, 4) where x is a real number.
This means that the points (-2, 4), (0, 4), and (2, 4) are all on the line $y=4$, and the y-intercept is 4.
Plot these points and connect them using a line.
