Question

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

anonymous · Answer

-5 - (-10) = 5
-3 - (-15) = 12

sqroot ( 5^2 + 12^2 ) = 13

lgbasallote · Answer

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

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