Conics and their Equations

Where does the 1/2 come from? Why did that seem especially tempting? What else is up here? What sort of help does this student need?

Thanks to Tina for the submission!

I make that 1/2 sort of mistake all the time: halfway up to the first point marked, which happens to be labeled 2 units.

I’m completely at a loss about how the second line came after the first. I’m also sad that people don’t seem to have the habit of plugging in a point or two in order to check their work.
