how is it - 2, 14?

OpenStudy (anonymous):

there is actually very little work to do here it is about \((-2,14)\) for the first one, but that is not an answer choice, the answer choice is somewhat more precise

oops i meant \(-2\) and \(14\)

you are solving for \(x\) so it is the first coordinate only looks like the first one (one on the left ) is somewhat greater than -2, go with -1.9

the first coordinate of that point is approx 2.6, that is how they got it and no, it is not A
