Question

A different telephone plan includes a monthly payment of $50 plus a charge of $0.05 per minute for calls. Write an equation for this function and identify the slope and y-intercept.

Answer 1

Answer:

y= 0.05x + 50

Step-by-step explanation:

Slope intercept form: y= mx + b

The total monthly cost of the telephone plan is $50 plus a charge of $0.05 per minute.

The charge is dependent on the minutes used.

Whenever we see per, we automatically have our slope.

Slope: 0.05

And since 50 is the independent variable, 50 is our y-intercept.

y= 0.05x + 50
