Linear Functions Graph Real World Non Proportional

The table shown is:

• Proportional, because it is going up by 2 each time.

• Linear, because it is going up by two each time.

• Not a function, because 1 appears in the table twice.

• A function but non linear, because it doesn't start at zero.

Mary buys concert tickets for $45 each plus a service fee of $15 for the order. This situation is:

• Proportional, because you can figure out the total cost.

• Linear, because all of the tickets are the same price, but non proportional because you add the service fee

• Not a function, because you have to pay a service fee.

• A function but non linear because each ticket costs more than the fee.
