1 answer:
9514 1404 393
Answer:
y = -17/6x -7/3
Step-by-step 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
