need to get the equation in y=mx+b form:
4x - 12y = 2
-12y = -4x + 2
y = (-4x+2) / -12
y = 4x/12 + 1/6
the slope of this line is 4/12. the slope of any line perpendicular to this line will have slope -12/4, or -3.
given the slope and a point, we can use this formula
(y - y1) = m(x - x1)
y - (-1) = -3(x - 10)
y + 1 = -3x + 30
y = -3x + 29
