1. The problem statement, all variables and given/known data For the given region R, find intR f(x) dA. The region has the following points: (-1,1), (-1,-2) and (3,-2) 2. Relevant equations 3. The attempt at a solution I'm having problems finding the boundaries for the integral. I know that we have: -1<=x<=3 and -2<=y<=1. I can also find the slope that it has and I found: y=-3/4x + 1/4. From there, I don't know what to do. I know i'm supposed to choose if I want to integrate first, does it matter? or how can I know which one is easier? I thought I could have something like: int(-1,3) int(1, -3/4x + 1/4) f(x) dA. Hope someone can help me with this!
