Count the amount of "spaces" between the two on a grid if you draw it on a paper.

tennistar · Answer

Could you do that? Like draw a graph and the two points and calculate the amount of coordinates.

anonymous · Answer

For two points A(x1, y1) and B(x2, y2) the distance between them is $$\sqrt{(x2 - x1)^2+(y2 - y1)^2}$$
So for your problem, A(9, -7) and B(9, 4), the distance between them would be 11.

Cogs explained it better than I could! Good job!

i wouldn't be able to tell i can't write well, my hand writing is messy really messy

tennistar · Answer

Thats ok. Just use the formula cogs gave to determine distance.
