[2] (a)(#35 Pg 439)(3 pts) On the figure at the right are the graphs of
[ x + y = 5 ] and [ y = 4x-1 ].
Without using a graphing calculator, express the area between the two graphs at the right as a single definite integral by entering specific integers (such as 3, -2, or 0) in the 6 empty answer boxes below. Show some algebraic work, especially in finding the two limit numbers a and b immediately to the right of the integral sign.
