M = (2 , - 4 )
given 2 points (x₁, y₁ ) and ( x₂, y₂ ) the coordinates of the midpoint are
midpoint = [ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ )
here (x₁, y₁ ) =( - 3, 0) and (x₂, y₂ ) = (7 , - 8)
midpoint = [[tex]\frac{1}{2}[/tex] (- 3 + 7 ), [tex]\frac{1}{2}[/tex] (0 , - 8) = ( 2 , - 4 )
