Answer:

The graph looks like the image below.

Explanation:

-2x means that every time x increases by 1, y increases by -2.

When y increases by -2, y decreases by 2.

Hence, as the x-value increases by 1, the y-value decreases by 2.

Also, the graph goes through the point (0, 0) since when x=0, y=0:

y=-2x ==> 0 = -2(0)
