Question

What is the length of the line segment in the x-y plane with end points at (-2,-2) and (2,3)?

Can anyone explain me how to make this one step by step?

Answer 1

You've got a formula. If the two endpoints are
`A(x_A,y_A)` and
`A(x_B,y_B)`, then the length is
`√((x_B-x_A)^2+(y_B-y_A)^2)`. The result is
`√(16+25)=√(41)`.
