Slope is 6/2 which also equals 3 because you have to use the rise over run process.
The answer would be 3 because 2 times 2 is 4 minus -1 would be 3
Let x dollars be your investment at 7%;
then the investment at 3% is the rest (1000-x) dollars.
The total interest equation is
0.07x + 0.03*(1000-x) = 0.061*1000.
Express x and calculate
x = %280.061%2A1000-0.03%2A1000%29%2F%280.07-0.03%29 = 775.
ANSWER. $700 is the 7% investment; the rest, (1000-775) = 225 dollars is the 3% investment.
