Question

How do you find the distance between point A(-3, 5) and point B(4, -6) in the coordinate plane?

Answer 1

AB= under root(x1-x2)^2 +(y1-y2)^2

=under root (4+3)^2 +(5+6)^2

= under root 49 + 121

= root 170

AB = 13.038

Answer 2

use formula for distance

d^2 =(X2-X1)^2+(Y2-Y1)^2

d^2=(4+3)^2 +(-6-5)^2

d^2=170
