Question

How many units apart are the points (4, -3) and (-4, 3)?

Answer 1

Use the distance formula:\[d = \sqrt{(x _{2}- x _{1})^{2}+ (y _{2}- y _{1})^{2}}\]

Where:
\[X _{1}= 4\]
\[X _{2}= -4\]
\[Y _{1}=-3 \]
\[Y _{2}= 3\]
Now plug it all in, what do you get?

Answer 5

Come on, does it seem reasonable that they are 100 points apart, when all of the coordinates are single digit numbers?

Answer 6

What did you forget to do?

Answer 7

square root it?

Answer 8

As my old math teacher used to say, "is that an answer, or a prayer?" :-)
