1) Based on the information below write a linear function that represents the heat bill each month for a household. Define the varables that you are using in the model.
HOURS THE
BILL AMOUNT FURNACE IS ON
$584.40 / 620 hours
$514.80 / 540 hours
$436.50 / 450 hours
Linear Function:

What does the slope represent to the household? (use a value in your explaination)

What does the y-intercept represent to the household? (Use a value in your explaination)

How many hours did a household have it's furnace on if the monthly bill was $288.60?
