What does it mean...2 coincidental lines?

anonymous · Answer

straight I think

mertsj · Answer

That is why you are having trouble.  Coincidental lines are lines that lie one on top of the other.  In other words...they are the same line.

mertsj · Answer

So now the question becomes...what points do they have in common?

not enough info right because he didn't give us the points

mertsj · Answer

What points do the two coincidental lines have in common?

mertsj · Answer

Take a red crayon and draw a line on your paper.

mertsj · Answer

Now take a green crayon and draw another line right on top of the red line.

mertsj · Answer

How many points do the two lines have in common?

anonymous · Answer

all of them

mertsj · Answer

Very good!!!!!

mertsj · Answer

And how many is that (look at your answer choices)

anonymous · Answer

The system has infinite solutions

mertsj · Answer

Is it 1 point, no points, an infinite number of points or not enough information?

mertsj · Answer

Way to go!!!  Good job.
