Answer:
y = 2
Coordinates (-3,2) is telling you that this point is going to be located in quadrant 2 if you were to graph it, because -3 is the x-coordinate and 2 is the y-coordinate. So if you want a line that passes through point (-3,2), the y-intercept has to be 2 hence y=2. This line is also parallel to line
y = -4.
Look at the graph I provided for a better visual.
