Question

PLZ HELP THANKS! Find the equation of the line passing through the pair points (-8,6) (-9,-9). The equation of the line in the form is Ax+By=C.

Answer 1

The answer is

15x - y = - 126

Explanation:

To find the equation of the line we must first find the slope (m)

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

So the slope of the line using points

(-8,6) (-9,-9) is

`m = ( - 9 - 6)/( - 9 + 8) = ( - 15)/( - 1) = 15`

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

15x - y = - 126

Hope this helps you
