Question

Find the distance between the two points. (−4, 7), (4, 0)

Answer 1

Distance²  =  (difference in 'y')² + (difference in 'x')²

                =                 (0 - 7)²  +  (4 + 4)²

               =                    49       +      64

               =                     113

Distance =        √113  =  approx. 10.63   (rounded)
