Answer:   y-9 = 17(x + 7)

====================================

Work Shown:

m = Slope

m = (y2-y1)/(x2 - x1)

m = (9-(-8))/(-7-(-8))

m = (9+8)/(-7+8)

m = 17/1

m = 17

Point slope form is

y - y1 = m(x - x1)

Plug in the slope m = 17, along with the point (x1,y1) = (-7, 9) to get the following

y - y1 = m(x - x1)

y - 9 = 17(x - (-7))

y - 9 = 17(x + 7)
