Determine if the points given are collinear: (-3,-3), (-1,0), (3,2). I worked out the problem and came up with a NO answer, can anyone double check this for me?

Question

How did you work it? Did you come up with equations, or did you graph the points?

anonymous · Answer

I graphed the points. (I haven't done math in 20 years and my instructor is not easy to follow, so I am sorta teaching myself at this point. Any and all help is much appreciated.

anonymous · Answer

If you can tell easily from the graph (as long as it is reasonably accurate). That should be enough to make a decision. If it doesn't ask you to justify your decision, then I think that is good enough.

Cool. Are you available for a little bit here, or do I have to 'post' post every question? (Again, I am new to this type of tutoring and don't know the formalities)

It's best to post each new question as a separate thread.

Sometimes, if there are two or three very similar questions (like exactly the same, just the numbers have changed), then they can be taken care of in a single thread of discussion.

OK ~ that will work for me. Thank you
