The line L has equation of 4x + 3y = 7. Find the equation of the line perpendicular to L which passes through the point of intersection of L and the yaxis. Give answer in ax + by + c = 0.

Math 
Steve,
slope of L: 4/3
slope of ┴: 3/4
L yintercept: 7/3
so, now you have a point and a slope:
y7/3 = 3/4(x0)
