Express the area of the shaded triangle in terms of "y".
I have attached a picture of the problem. As you can see, I have already tried to solve the problem, but to no avail. I cannot figure it out at all. Any ideas?
The answer is to be in terms of y.
Every point ont your line is $\displaystyle (4-2y,y)$
The width is $\displaystyle 4-2y$ and the length is $\displaystyle y$.
What is the area?

So the width is $\displaystyle 4y - 2y^2$? ok..I see it now.
