4 units. Plot the two point and connect them with a line. You can now make a right triangle. The line you plotted is the hypotonuse. Use the pythagorean theorem to find the distance between A and B is 4 units.
To find the distance between 2 points, you have to use the distance formula: [tex] \sqrt{(x_{2}- x_{1})^{2} +( y_{2}- y_{1})^2 } [/tex]. Fill in your numbers, and you got this: √((-2) - (-3))² + (7 - 3)², which equals about 4.123.
