Question

Find the distance for the following two points A (-10,-15) (-5, -3).
1) 13
2) -13
3) 12
4) -12

Answer 1

-5 - (-10) = 5
-3 - (-15) = 12

sqroot ( 5^2 + 12^2 ) = 13

Answer 2

\[distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\] \[distance = \sqrt{[-5 - (-10)]^2 + [(-3 - (-15)]^2}\] \[distance = \sqrt{(-5+10)^2 + (-3 + 15)^2}\] \[distance = \sqrt{(-5)^2 + (12)^2}\] \[distance = \sqrt{25 + 144} \] \[distance = \sqrt{169}\] \[distance = 13\]

Answer 3

In the fourth step is positive 5 even do it doesnt affect the final result
