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 130 minutes, the monthly cost will be $57. if the customer uses 780 minutes, the monthly cost will be $187. a) find an equation in the form y = m x + b , y = m x + b , where x x is the number of monthly minutes used and y y is the total monthly of the a fee and fee plan.

The equation is in the form of is .

Explanation:

We have to find the equation in the form of . It is a linear equation.

Where, x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan.

If a customer uses 130 minutes, the monthly cost will be $57. If the customer uses 780 minutes, the monthly cost will be $187. When the data is written in the form of coordinate pairs we get (130,57) and (780,187).

The equation of line passing through two points and is given below,

We have two points (130,57) and (780,187) so the equation of line is,

Therefore, the equation is in the form of is .

1/5x+9 2/5y+7
