    y=-1/2x-5

    Step-by-step explanation:

    First we need to put (y-3) = 2 (x-4) in slope intercept form.

    we need to do order of operations ...

    so we need to first do the parenthesis

    x*2 = 2x

    2*-4 = - 8

    y-3=2x-8

    add 3 on both sides to isolate y

    y = 2x-5

    so now we know the y=mx+b form

    this is one line ...

    now we need to find out what line is perpendicular.

    Perpendicular lines have opposite reciprocals slopes.

    y=-1/2x-5
