triangle ABC A is (-3,1) B is (5,-3) C is (1,7)

find the equations of:
the median AM
And
the perpendicular bisector of BC

  • Mathsssssssssssss -

    Middle of BC is
    ( (1+5)/2 , (-3+7)/2) )
    or
    (3,2) is point M
    so
    line through (-3,1) and (3,2)
    I bet you can find that line.

    Then
    line through M perpendicular to BC
    slope of BC = 10/-4 = -5/2
    so slope we want = 2/5
    so line with m = 2/5 that goes through (3,2)
    I bet you can do that too.
