To graph the proportional relationship y = -2x, we can choose a few points and plot them on a graph.
When x = 0, y = 0
When x = 1, y = -2
When x = 2, y = -4
When x = -1, y = 2
When x = -2, y = 4
Plotting these points on a graph, we get a straight line passing through the origin with a slope of -2.
The graph of the proportional relationship y = -2x is a line that passes through the origin and has a slope of -2.
