Question

WILL GIVE BRAINLIEST find the value of (-4,r), (-8,3), m=-5 (show your work pls)

Answer 1

Answer:

r = -17

Step-by-step explanation:

Slope = -5

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\frac{3 - r}{-8-[-4]}=-5\\\\\frac{3-r}{-8+4}=-5\\\\\frac{3-r}{-4}=-5$

3-r = (-5)*(-4)

3 - r = 20

   -r = 20 - 3

  -r = 17

   r = -17

Answer 2

r=-17 the person above is right
