Linear functions are transformations of what two types of functions?
Definition
Linear functions are transformations of the identity function or constant function.
Term
What is the solution to an equation?
Definition
The solution to an equation is the values of the variables that make the equation true. If there are two variables, the solution is also a point on the graph.
Term
