Hi there new here. This seems like a really easy question but can't get it:

basically standard form of ellipse:

Here's the question: ''pass through (2,2) and (1,4)''Code:x2 y2 -- + -- = 1 a2 b2

plz solve, thanks!

(what I did: filled in two of these equations with this info on top and two sets of unknown a's and b's, but have no idea where to take it after that.)
