Question

Help! Please! I will give medal! Find the distance between the two points using the distance formula:
Point C: 3,2
Point D: 7,-2

Answer 1

Do you know about the distance formula?

Answer 2

yeah but every time I get 0

Answer 3

\[d = \sqrt{( x _{2}- x _{1})^{2} + (y _{2}-y _{1})^{2}}\]
Set your problem up.
\[d = \sqrt{(7 - 3)^{2}+(-2 + 2)^{2}}\]
Simplify.
\[d=\sqrt{(4)^{2} + (0)^{2}}\]
That 0 gets erased and you're left with...
\[\sqrt{16}\]

Answer 4

And so your distance will be 4.

Answer 5

oh my gosh thank you so much!

Answer 6

You're welcome :)
