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:

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

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

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

$D = \sqrt{(2 - 2)^2 + (0 - (-2))^2}$

$D = \sqrt{(2)^2}$

$D = 2$

The distance is 2 units long.
