Write an equation in slope-intercept form, y = mx+b, using the given
likoan [24]

Answer:

y = \frac{-4}{3}x - 15

Step-by-step explanation:

with the point slope form, plug -9 (x coordinate) into x1, -3 (y coordinate) into y2, and -4/3 (slope) into m

y - y2 = m(x - x1)

y - (-3) = -4/3 (x - (-9))

y + 3 = -4/3 (x + 9)

y + 3 = -4/3 x + -12

y = -4/3 x - 12 - 3

y = \frac{-4}{3}x - 15
