  1. (1) Slope of BC, B(-1,2), C(6,-6)

    m= y2-y1/x2-x1

    m= -6-2/6+1

    = -8/7


    Let AD⊥ BC

    (slope of AC)( slope of BC) = -1

    (m1)(-8/7) = -1

    (m1) = 7/8

    And AD is passing through A(3,8)

    equation of a line

    (y-y1)= m1(x – x1)

    y-8= 7/8(x-3)

    8y-64= 7x-21
