Answer:

y = -17/6x -7/3

Explanation:

The 2-point form of the equation for a line can be a useful place to start.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (-8 -9)/(2-(-4))(x -(-4)) +9

y = -17/6(x +4) +9 . . . . . simplify a bit

y = -17/6x -11 1/3 +9 . . . eliminate parentheses

y = -17/6x -7/3 . . . . . . . collect terms
