Determine the distance between the points plotted on the graph. Round your answer to the nearest tenth.

Question

The points are: (-2,5) and (-5,-2)
My answer is: 9.9
My work:
(-2,-5)^2 + (5-(-2))^2
= (-7)^2 + (7)^2
= 49 + 49
= 98; square root of 98: 9.9

Answer 1

Not quite...
-2 - - 5
= -2 + 5
= 3

Answer 2

I re-did it and got
(-2-(-5)^2 + (5-(-2))^2
= (3)^2 + (7)^2
= 9+49
=square root of 58
=7.6

Did I do it right this time?

Answer 3

7.6 is correct.
