The Mathalot Company makes and sells textbooks. They have one linear function that represents the cost of producing textbooks and another linear function that models how much income they get from those textbooks. Describe the key features that would determine if these linear functions ever intercepted.

Two straight lines intersect at ONE point only if ... what?
What about the y-intercepts of these two straight lines?  What could you say about them?

solomonzelman · Answer

ogh, I see... I always hated these type of questions that ask you for these concepts without any specific example or specific information.

anonymous · Answer

I still don't get it

mathmale · Answer

Hints:

1.  If two linear equations have the same slope, but different y-intercepts, they will NEVER intersect.
2.  If two linear equations have the same slope and the same y-intercept, they coincide (and have infinitely many intersections).
3.  If two linear equations have different slopes, and are in the same plane, they WILL intersect at ONE point (they will have a unique solution).

With this information, choose your own response to this question.

So it would be #3?

mathmale · Answer

You will need to decide that for yourself.
