Question

What is the distance between `(2,3)` and `(0, 4)`?

Answer 1

The distance is `sqrt5`.

Explanation:

Using the formula of distance between two points:

`d = sqrt((y_2-y_1)^2 + (x_2-x_1)^2)`

where the first point has coordinates `(x_1, y_1)` and the other point has coordinates `(x_2, y_2)`.

So, we get that:

`d = sqrt((4-3)^2 + (0-2)^2) = sqrt(1^2 + (-2)^2) = sqrt(1 + 4) = sqrt5`.
