(0, 0), (3, 5), (1, 8)(adsbygoogle = window.adsbygoogle || []).push({});

Find the slopes and equations for each line

(0,0) ----> (3,5) = 5/3x

(0,0)---->(1,8) = 8x

(1,8)---->(3,5) = -3/2x+ 19

Then I set up the integrals (on x)

Integral sign from 0 to 1 (8x-5/3x)dx + Integral sign from 1 to 3 [(-3/2x+19)-5/3x) dx

I got 117/4 as an answer and that's wrong. My algebra/arithmetic isn't wrong (i triple checked it) so it must have something to do with the set up. What's wrong with it?
