On a coordinate plane, a line is drawn between point (x 2, y 2) and (x 1, y 1).
Which equation would find the distance between the two points show on the coordinate plane?
d = StartRoot (x 2 + x 1) squared + (y 2 + y 1) squared EndRoot
d = StartRoot (x 2 minus x 1) squared minus (y 2 minus y 1) squared EndRoot
d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot
