Question

What is the distance from the dance hall (-2,2) to the university (0,2)

Answer 1

Remember the formula for the distance formula:

`D = √((y_2 - y_1)^2 + (x_2 - x_1)^2)`

where
`(x_1, y_1)` and
`(x_2, y_2)` are coordinates

Given this formula, we can simply insert our points into the formula:

`D = √((2 - 2)^2 + (0 - (-2))^2)`

`D = √((2)^2)`

`D = 2`

The distance is 2 units long.
