Question

Find the distance between the points \[\left(- \frac{8}{5}, 2 \right)\] and \[\left(\frac{2}{5}, 2 \right)\].

Answer 1

We have to find the distance between `A (-8/5, 2)` and `B (2/5, 2)`.

In general, the distance between `A(x_1, y_1)` and `B(x_2, y_2)` is given by,

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

So,

`AB = sqrt((2/5 + 8/5)^2 + (2 - 2)^2)`

`= sqrt(4)`

= 2
