Question

How do you calculate the distance between F = (2,2) and M = (5,-4)?

Answer 1

The answer is `D=sqrt45=3sqrt5`

Explanation:

The formula between two points in cartesian coordinates is

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

hence we replace the coordinates of the two points in the formula above and we get

`D=sqrt((2-5)^2+(2+4)^2)=sqrt(9+36)=sqrt45`
