Hey!
--------------------------------------------------
Steps To Solve:
Slope Formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
~Substitute with the coordinates given
[tex]\frac{-6 - r}{0 - 1}[/tex]
~Simplify
[tex]\frac{-6 - r}{-1}[/tex]
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 [tex]\Large\boxed{\mathsf{-10}}[/tex]
