M is the midpoint ofSymbol for segment A B..
Line segment A B, with point M as its midpoint. A M equals M B.

Find the coordinates of B given A(3,8) and M(5,4)

  • geometry -

    Double the deltaX and deltaY differences from A to M, and add them to the A coordinates.

    deltaX = 5-3 = 2
    deltaY = 4-8 = -4

    Take it from there.
