Each ordered pair is (x,y). Determine the coordinates by substitution.
for (15,y):
y=1/3 * 15 - 9
y=-4
for (x,-6):
-6=1/3x -9
1/3x=3
x=9

Answer: 2285.71
Step-by-step explanation:
Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.
r = R/100 = 5%/100 = 0.05 per year.
Solving the equation:
P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143
