Question

What is the distance between point P and point R?

Answer 1

Answer:

PR = 10

Step-by-step explanation:

PR = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The coordinates for P and R are (0,4) and (-6,-4) respectively.

So you plug in the values:

PR = $\sqrt{(-6-0)^2+(-4-4)^2}$

PR = $\sqrt{(-6)^2+(-8)^2}$

PR = $\sqrt{36+64}$

PR = $\sqrt{100}$

PR = 10
