Answer:

r=-10

Explanation:

slope =(y2-y1)/(x2-x1)=-4

(-6-r)/(0-1)=-4

Hey!

--------------------------------------------------

Steps To Solve:

Slope Formula:
(y2-y1)/(x2-x1)

~Substitute with the coordinates given


(-6 - r)/(0 - 1)

~Simplify


(-6 - r)/(-1)

Now we can solve for r.

~Simplify the equation.

r + 6 = -4

~Subtract 6 to both sides

r + 6 - 6 = -4 - 6

~Simplify

r = -10

--------------------------------------------------

Hence, the value of r is
\Large\boxed{\mathsf{-10}}

--------------------------------------------------

Hope This Helped! Good Luck!
