Answer:y = -2x
Step-by-step explanation:
slope-intercept form is as follows
y = mx + b
You are given that the slope is -2 and since the line passes through the origin, there is no y-intercept
So you just plug in the slope
y = -2x + b
And since there is no y-intercept, you can take that out.
y = -2x
