Question

Is it 11 or -11?

What is the distance between points (9, –7) and (9, 4) on a coordinate plane?

Answer 1

1,3 i think

Answer 2

1,-3

Answer 3

D= sqrt[(y1-y2)^2+(x1-x2)^2]

Answer 4

D=sqrt[(-7-(4))^2+(9-9)^2]=sqrt(11)^2=11

Answer 5

one thing distance always positive

Answer 6

Oh okie. Thnx! :)
