Distance Formula

Question 3

Find the length of the line segment AB where point A is at
( 0, 2 ) and point B is at ( -1, - 4 ).

Solution

Label the points as ( x1, y1 ) = ( 0, 2 ) and ( x2, y2 ) =
( -1, - 4 )
. Therefore, x1 = 0, y1 = 2, x2 = -1, and y2 = - 4.

To find the distance d between the points, use the distance formula :
