Answer:

15x - y = - 126

Explanation:

will make it simple and short

first we need to find the slope (m) first in order to get the equation

given: (-8,6) (-9,-9)

y2 - y1 -9 - 6

Slope = m = ----------- = ------------------ = 15

-x2 - x1 -9 - (-8)

so the equation of the line using point (-8,6) and slope 15 is y - 6 = 15( x + 8)

y - 6 = 15x + 120

using the form equation Ax + By = C, 15x - y = -120-6

therefore... 15x - y = - 126 is the answer
