Question

What is the distance between `(-13,12)` and `(12,-2)`?

Answer 1

≈ 28.65

Explanation:

To calculate the distance between 2 points , use the `color(blue)" distance formula "`

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

where`(x_1,y_1)" and " (x_2,y_2)" are 2 coordinate points "`

let `(x_1,y_1)=(-13,12)" and " (x_2,y_2)=(12,-2)`

`rArr d = sqrt((12-(-13))^2 + (-2-12)^2) = sqrt(625 + 196)`

`= sqrt821 ≈ 28.65`
