Answer 3

I think about this as if the point (2,1) were "inked" and the the upper half of the graph folded about the x-axis, then on what point below the x-axis would the point (2, 1) fall.

Answer 4

The 2 in (2,1) would still be 2, but where would the 1 in (2,1) fall?

Answer 5

would it be (2.-1)

Answer 6

Yes, that is what I got.

Answer 7

ok thank you

Answer 8
