Answer:
The interest rate was of 5.5% a year.
Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
In this question, we have that:
We have to find r.
Taking the square root from both sides to isolate r.
The interest rate was of 5.5% a year.
You change the equation into a y=mx+b form so it would be y=x-6 and so when you graph it, go down six on the y-axis and make a straight line that goes diagonally through the boxes. Not sure if you were asking how to change the equation to graphing form or how to actually graph the line but hopefully this helps. :)
