Asked by John

Hey. I was wondering if someone could help me with this question? I asked my teacher to explain it to me, but I still don't get it. I don't care for an answer, I just want to know how to solve. Thanks in advance.

- A (-3, -4)
- B (5, 2)
- C (11, -6)

What is AB?

(I just don't know what they mean by AB? Surely they don't want me to multiply them, do they?)

We have line AC with end points A and C.
B is a point on line AC.
AB is a portion of AC.
AB = sqrt((5+3)^2 + (2+4)^2) = 10.

A, B, and C are not colinear ... they don't lie on the same line

AB is the distance between A and B ... distance formula?

Oops! I agree.
