Step-by-step explanation:
First you plot -4 on the y-axis at -4. Since the slope is -4x, you move your dot up 4 times than move it left once. Keep doing that until you think you have enough. Use a ruler to connect your points.
Same for #2.
This time Y is at positive 2 on the Y-axis. For this slope move y up once and than left once. Do it until you have enough dots than connect your dots in a straight line
