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.

The question is asking to explain or described the key features that would determine if the linear functions is ever intercepted base on the said equation and the function, I would say that the answer would be 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).
