How is the distance formula correctly written? Options: $$d\ =\ \sqrt{\left(y_{1\ }-\ y_2\right)^2\ -\left(x_{2\ }-\ x_1\right)^2}\ $$ , $$d\ =\ \sqrt{\left(x_{2\ }-\ x_1\right)^2\ +\ \left(y_{2_{\ }}-\ y_1\ \right)2}$$ , $$d\ =\ \sqrt{\left(y_{1\ }-\ y\ _2\right)^2\ +\ \left(x_{2\ }-\ x_1\right)}^2$$ , d = $$\sqrt{\left(x\right)^2-\ \left(y\right)^2}$$

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

If two lines are perpendicular to each other, their slopes are ____________

negative reciprocals of each other.

A(3,1) B(-2,-1) written correctly is: Options: $$\sqrt{\left(-2-3\right)^2\ +\ \left(-1-1\right)^2}$$ , $$\sqrt{\left(1-3\right)^2\ +\ \left(-1-2\right)^2}$$ , $$\sqrt{\left(-2-3\right)^2\ -\ \left(-1-1\right)^2}$$ , $$\sqrt{\left(-2-3\right)^2\ -\ \left(-1-1\right)^2}$$

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