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. <0|ΙΈ|0> -Joe- |
