Answer:

y = -6x -9

Explanation:

To write the equation of the line we need to ensure that we have the two points which it passes through.

For our given line let's pick (-2,3) and (1,-9)

Slope = Rise/Run

= ∆y/∆x

= -9-3/1+2

= -12/3

= -6.

we now have the slope. to write an equation we need the slope, one of the known points and one unknown point. we take (-2,3) and (X,y)

Slope = ∆y/∆x

-6 = y-3/X+2

-6(X +2) = y-3

-6x -12 = y-3

y = -6x -9
