Find the slope of the line thr
points.
(20, 17) and (5, -4)

m = 7/5 [Slope]

Explanation:

The first method uses the point slope equation/formula: y - y1 = m ( x - x1 ).

Where (x1,y1) is the initial point, (x,y) is the final point), and m is the slope of that line.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
