The phone company A Fee and Fee has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 270 minutes, the monthly cost will be $93.5. If the customer uses 670 minutes, the monthly cost will be $193.5. A) Find an equation in the form y=mx+b, where x is the number of monthly minutes used and yy is the total monthly of the A Fee and Fee plan. B.) Use your equation to find the total monthly cost if 951 minutes are used.

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
