ivanzaharov [21]

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

y =mx+b

where y is monthly cost, x is the number of minutes, b is the flat monthly fee, and m is the slope of the equation, or in our case, the amount of money charged per minute.

The slope m is

m= \dfrac{\$372.5-\$131}{990min-300min}

m = \$0.35/min,

in other words, the phone company charges $0.5 per minute.

With the slope in hand, the linear equation becomes

y =0.35x+b,

and we can find the monthly fee b from that fact that for 300 minutes the cost is $131:

\$131 = 0.35(300min) +b

b = \%26.

Therefore,

y = 0.35x+26

where the slope if the equation give the cost per minute of the phone used.
