I'm doing a review of Graphing Systems of Equations.

y=5/3x-1
y=3x-5

I've positioned both lines correctly (I've verified the position using the Show Me buttons in the "hints").

I enter 3 for the value of x
I enter 4 for the value of y

The hint answer indicates that this is correct with "The lines intersect at (3,4)."

There is a magenta circle at the point where my lines intersect, also convincing me that I have the correct solution.

However, I get the frowny face and my progress bar goes down (this has happened several times due to leaving and coming back to the review in hopes of a full refresh fixing the problem).
