    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.
