Which of the following is an equation of the line through (3, -1) and (−2, 14)?

A) y = 1/3x - 2

B) y = -1/3x

C) y = 3x - 10

D) y = -3x + 8

Respuesta :

D.
Slope is rise over run and in this case it is -15/ 5 so when it is reduced you get -3 as your slope
D.Y2-Y1=M(X2-X1)
14-(-1)=M(-2-3)
15=M(-5)
15/-5=M
-3=M
If the slope is -3, the answer is D
