What is the distance, in units, between the points \((-3, -4)\) and \((4, -5)\)? Express your answer in simplest radical form.

(-3, -4) and ( 4, -5)......the distance is given by

sqrt [ ( -3 - 4)^2 + ( -5 - -4)^2 ] =

sqrt [ ( -7)^2 + (-1)^2 ] =

sqrt [ 49 + 1 ] =

sqrt [ 50 ] =

sqrt [ 25 * 2 ] =

sqrt (25) * sqrt (2) =

5*sqrt (2)

Thanks!
