Question

What is the distance between point P and point R?

Answer 1

PR = 10

Explanation:

PR =
`√((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 =
`√((-6-0)^2+(-4-4)^2)`

PR =
`√((-6)^2+(-8)^2)`

PR =
`√(36+64)`

PR =
`√(100)`

PR = 10
