Answer
slope = 0
y-intercept = -2
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=-2 is a horizontal line with a slope of zero and contains all the points (x, -2) where x is a real number.
This means that the points (-2, -2), (0, -2), and (2, -2) are all on the line y=-2, and the y-intercept is -2.
Plot these points and connect them using a line.
