What is a term?
300
A set of input values that consists of only certain numbers in an interval
What is Discrete Domain?

Do all linear functions have to have a slope? In other words, does a straight vertical line represent a linear function?
Linear Fuctions must have slopes. A vertical line does not represent a linear function.
300
A function defined by two or more equations
