Here is an equation that represents a function: \(72x+12y=60\).

Select all the different equations that describe the same function:

1. Graph a system of linear equations with no solutions.
2. Write an equation for each line you graph.

Here is an input-output rule for a function: Multiply by 4, then add 2.

1. Complete the table with the outputs that go with a given input. Then add two more input-output pairs to the table.

   input	output
   0
   -3
   4
   \(\frac25\)

2. Write an equation to represent the function.
3. What letter did you use for the independent variable? The dependent variable?

Solve each equation, and check your answer.
