If tax was 8% on the flowers Jorge bought in the previous problem what was the total cost?

The table shows the balance of a money market account over time. write a function that represents the balance y(in dollars) after t years.

Can someone answer this question for me

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
