(-1, 2)

=============

Find the coordinates of the midpoint of AB.

The midpoint formula is given by:

  • Midpoint = ((x₁ + x₂)/2, (y₁ + y₂)/2)

Given that the midpoint is M(2, -2), and the coordinates of A are (5, -6), we can substitute these values into the formula:

  • 2 = (5 + x₂)/2
  • -2 = (-6 + y₂)/2

Simplifying these equations, we get:

  • x₂ = 2*2 - 5 = 4 - 5 = -1
  • y₂ = - 2*2 - (-6) = - 4 + 6 = 2

Therefore, the coordinates of B are (-1, 2).
