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
