Distance2 = (21-9)2 + (16-11)2 = 169 and the square root of this is the distance which is 13 units
The distance formula takes the difference between the two x-coordinates (9-3 = 6) and the difference between the two y-coordinates (-4-7 = -11), then squares these two answers (62 = 36 and (-11)2 = 121), then adds them together (36 + 121 = 157), then takes the square root of this final number. Thus the distance between (9, -4) and (3, 7) is sqrt(157), or about 12.53.

11 points
If you mean points of (21, 16) and (9, 11) then the distance works out as 13
If you mean points of (21, 16) and (9, 11) then the distance works out as 13

If you mean points of (1, -2) and (-9, 3) then the distance is about 11 units using the distance formula
Distance2 = (21-9)2 + (16-11)2 = 169 and the square root of this is the distance which is 13 units
If you mean points of (1, -2) and (-9, 3) then it works out as about 11
If you mean endpoints (-1, -3) and (11, -8) then by using the distance formula the length between the points is 13 units
It is 51 - (-11) = 62.
The distance between these two places is 11 miles. This distance is only approximate. This is not the exact distance.
