Double Integral with Triangle Vertices

[Leeyumm5]

Hey guys, I've been working on this one problem for the past couple days and can't figure out what I'm doing wrong, any help would be greatly appreciated. I attached a picture of the problem along with the work that I've done so far, thank you!

It seems you have a mistake in the beginning - while calculating the equation of the bdy. line. Please fix it and recalculate the equation of the bdy. line.

However, excellent "clean" work.
