Answer 2

hmm what's A and B coordinates anyway?

Answer 3

Did you open the link......

Answer 4

yes, what did you get?

Answer 5

I came on here because I don't know how to do it.....

Answer 6

\(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
A&({\color{red}{ \square }}\quad ,&{\color{blue}{ \square }})\quad B&({\color{red}{ \square }}\quad ,&{\color{blue}{ \square }})
\end{array}\qquad
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)

Answer 7

get the coordinates for A and B, and plug them in the distance formula

Answer 8

A?

Answer 10

hmm dunno.. what did you get for the coordinates for A and B?

Answer 11

8 and 10...that's probably wrong though. :( @jdoe0001

Answer 13

well.. to find the coordinates, recall that you have to use the "x" and the "y" axis for example

Answer 14

D?

Answer 15

@jdoe0001 D?

Answer 16

hmm dunno... get A and B coordinates and plug them in the distance formula

Answer 17

Nevermind I'll ask someone else....
