The answer is
<h2>15x - y = - 126</h2>Step-by-step explanation:
To find the equation of the line we must first find the slope (m)
So the slope of the line using points
(-8,6) (-9,-9) is
So the equation of the line using point (-8,6) and slope 15 is
y - 6 = 15( x + 8)
y - 6 = 15x + 120
Writing the equation in the form
Ax+By=C
We have
15x - y = -120-6
The final answer is
<h3>15x - y = - 126</h3>Hope this helps you
