Question

What is the length of segment AB?

A coordinate plane is shown. Point A is located at 6, 2, and point B is located at 0, 10. The points are connected by a line segment.

Answer 1

To solve this problem we will need the distance formula between two points with coordinates P1(x1,y1) and P2(x2,y2).

Distance formula

Distance = sqrt((x2-x1)^2+(y2-y1)^2)

=sqrt((0-6)^2+(10-2)^2)

=sqrt(36+64)

=sqrt(100)

=10 units.
