Distance Formula

Question 1

Find the distance between the points ( 1, - 4 ) and ( - 4, 2 ).

Solution

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

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