Question

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?

Answer 1

17 units

Explanation:

Use the distance formula,
`d = √((x_2 - x_1)^2 + (y_2-y_1)^2)`

Plug in the points and simplify:

`d = √((x_2 - x_1)^2 + (y_2-y_1)^2)`

`d = √((-8 - 7)^2 + (0-8)^2)`

`d = √((-15)^2 + (-8)^2)`

`d = \sqrt{225 + 64`

`d = \sqrt{289`

`d = 17`

So, the distance between the points is 17 units
