Find the distance between the points -1 4 and 2 -3?

The required distance is the hypotenuse of a right triangle with sides of lengths [2 - (-1)] and [4 - (-3)] = 3 and 7 respectively. From the Pythagorean theorem, this distance is the square root of the sum of the squares of the lengths of each side, in this instance the square root of (9 + 49) or the square root of 58. There is no integral square root, but the decimal approximation is about 7.616 units.
