Question

The library is located at (-4, 5) and the school is located at (4,5). If each unit on the coordinate plane represents ¼ of a mile, how far away from each other are the school and library?

Answer 1

2 miles

Explanation:

`d=\sqrt{(-4-4)^(2)+(5-5)^(2)`

`d=\sqrt{(-8)^(2) } =8` units

if each unit represents 1/4 miles in the plane, then

`d=8(1/4)=2 miles`

Hope this helps
