Distance Formula

$$\sqrt{\left(-2-3\right)^2\ +\ \left(-1-1\right)^2}$$

$$\sqrt{\left(1-3\right)^2\ +\ \left(-1-2\right)^2}$$

$$\sqrt{\left(-2-3\right)^2\ -\ \left(-1-1\right)^2}$$

$$\sqrt{\left(-2-3\right)^2\ -\ \left(-1-1\right)^2}$$

$$d\ =\ \sqrt{\left(y_{1\ }-\ y_2\right)^2\ -\left(x_{2\ }-\ x_1\right)^2}\$$

$$d\ =\ \sqrt{\left(x_{2\ }-\ x_1\right)^2\ +\ \left(y_{2_{\ }}-\ y_1\ \right)2}$$

$$d\ =\ \sqrt{\left(y_{1\ }-\ y\ _2\right)^2\ +\ \left(x_{2\ }-\ x_1\right)}^2$$

d = $$\sqrt{\left(x\right)^2-\ \left(y\right)^2}$$
