Answer:

  y = -7x

Step-by-step explanation:

The line goes through the origin, so the y-intercept is b=0.

The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...

  m = rise/run = -7/1 = -7

Then the slope-intercept form equation is ...

  y = mx + b

  y = -7x
