# Distance Between Two Points on a Cartesian Plane

## Distance Between Two Points on a Cartesian Plane

In a Cartesian coordinate system in the plane, the distance d between two points $$(x_1, y_1$$) and ($$x_2, y_2$$) is: d = $$\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}$$.

### Example

The distance d between the points P(1, 2) and Q(4, 6) is: d = $$\sqrt{(4-1)^{2}+(6-2)^{2}}$$ = $$\sqrt{25}$$ = 5.
