Answer:
y = -2/3 (x+3) + 2
Step-by-step explanation:
use the point-slope form equation: y - y1 = m (x - x1)
plug in the point (-3,2) and slope -2/3 into the equation:
y - 2 = -2/3 [x - (-3)]
you can simplify it:
y - 2 = -2/3 (x+3)
and you can also put it in terms of y:
y = -2/3 (x+3) + 2
Answer:
-131
Step-by-step explanation:
(0 − 3) − 8(12 + 4) =
= -3 - 8(16)
= -3 - 128
= -131
