Conditional Expectation Problem

Hi everybody, I have problems trying to solve a expectation problem.

The question is:

Two continuous random variables A and B are uniformly distributed over the triangle defined by (0,0), (2,6) and (6,0) in the A-B plane.
Need to calculate E(Y/X | Y=4)

Does anybody know how to solve this problem?

Thanks

You need to draw it out...

You want the of area bounded by your triangle and 4/x.
