Here's one way. If your Statistics 2Var app is still in its default state, then you can solve this:

(x,y)1 = (1,5)
(x,y)2 = (7,17)
(x,y)3 = (10,?)

by doing this, from the Home keyboard:

C1:={1,7} [the two X values]
C2:={5,17} [the two Y values]
PredY(10) Enter --> 23, answer.

As Tim mentioned, PredX also exists. It predicts an X from a Y value:
PredX(23) --> 10.
