Answer:
9x- y = 79
Step-by-step explanation:
Use the formula y - y1 = m (x - x1)
point: (-9,-2) x1= -9 y1= -2
slope: -9
plug everything in y + 2= -9 (x + 9)
simplify y + 2= -9x - 81
move the 2 to the other side y = -9x - 79
move the -9x to the other side -9x + y = -79
multiply the whole thing by -1 to make the x positive
9x - y = 79
