Answer:

  y = -8x -15

Step-by-step explanation:

It can be useful to start with the point-slope form when you are given a point and a slope.

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

For the given line, this equation is ...

  y +7 = -8(x +1)

  y = -8x -8 -7 . . . . eliminate parentheses, subtract 7

  y = -8x -15 . . . . . slope-intercept form
