# Iterated integral

## Main Question or Discussion Point

How can I find the lower bound for an iterated integral in this case?

My attempt:

y = (-5/4)x+5 (which represents the line)

But it doesn't work.

Why do you say it doesn't work? That is the equation of the lower line.

I am confused too. = (

only c is wrong.

but y = (-5/4)x+5 is only applicable till y = 2.5 though.

Maybe they're looking for -1.25 for the slope instead of -5/4.

Tried both ways. = (

It looks to me like that one corner point is at (2, 2), not (2, 2.5). That would make the equation of the line y = -x + 4.
