Prove It
Re: Collinear Points
What have you tried? What does it mean for points to be collinear? It means that they're all on the same line. Can you find the equation of a line which satisfies all three points?

What is the slope of $\overleftrightarrow {AB}~?$ What is the slope of $\overleftrightarrow {AC}~?$

@brosnan123, you have posted several questions with on evidence that you have made any effort whatsoever.

This is not a homework service.

Post some of your own work.
