Quiz about Slope, Midpoint, Distance

Question 1

How is the distance formula correctly written:

Accepted Answer

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

Answer

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

Answer

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

Answer

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