Question

Which equation can be used to determine the distance between the origin and (-2, -4)?

O d= V((0-2)+(0-4))2
O d= V0-(-2)2 + (0-(-4))2
O d= V((0-2)-(0-4)2
O d(0-(-2)2 – (0-(-4)2

Answer 1

`~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-2}~,~\stackrel{y_1}{-4})\qquad \underset{origin}{(\stackrel{x_2}{0}~,~\stackrel{y_2}{0})}\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√([0 - (-2)]^2 + [0 - (-4)]^2)`
