Iterated integral

    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.

    What tells you that it is wrong? Is the final value of the integral wrong or do you get an error message? Do you need a multiplication sign (-5/4)*x+5?
