distance and midpoint between points

Question

Find the distance between points A and B also find the midpoint. A (x1, y1) = (2, -4) B(x2, y2) = (10, -10)

Answer 1

Distance between the points AB = √(x2-x1)^2+(y2-y1)^2

= √(10-2)^2+(-10+4)^2

= √64+36

= √100

= 10

Midpoint of AB = (x1+x2/2 , y1+y2/2)

= (2+10/2 , -4-10/2)

=( 6,-7)
