Inverting the Y Axis

Invert Y axis on coordinate plane? On a coordinate plane, what is the equation to flip the image upside down? Could it be as simple as y = −y? Yes, probably. I will implement the equation in my code and get back to you. There's a deeper problem in my code. I'll mark this as answered.

A Stack Overflow-style question asks how to flip an image upside down on a coordinate plane. The suggested equation is wrong because it should be y = -y, but the joke is that the asker discovers an even deeper problem in the code and marks the question answered anyway.
