so midpoint is basically the middle of two points
in this question, we would use the formula
m = [ (x₁ + x₂) ÷ 2 , (y₁ + y₂) ÷ 2 ]
see attachment, if you don't get the formula
so basically, we add the two x-coordinates and divide them by 2
and add the two y-coordinates and divide them by 2
which will give you (-3, -1)
because (-5) + (-1) ÷ 2 = -3 (x-coordinate)
and 4 + (-6) ÷ 2 = -1 (y-coordinate)
