Find the distance between (7, -11) and (1, -3).

Question

I can do math just graphing i cant but that's all i need help with

 

Answer 1

You need to use the Distance Formula.

 

It's the square root of THE SUM OF THE SQUARES OF THE DIFFERENCES IN X AND Y.

 

The "x difference is 6"; the y difference is 8 (or -8, if you wish) so the sum of 36 + 64 gives you 100, and therefore the answer is √100 = 10.

 

I feel confident that your textbook will shed some light onto the matter.
