Let gradient of original line = m = 1/6
Gradient of line perpendicular to this = -1/m = -6
(Gradient = slope)
To find the answer for A you add up the interest rate for 2 years which is 16% then find 16% of $9,000 which is $1,440 and that's his interest rate he will have to pay for 2 years. If you want to know how much he has to pay in total for 2 years you simply just add the interest rate $1,440to $9,000 and you get $10,440.
To find the answer for B you add up the interest rate for 6 years which is 48% then find 48% of $9,000 which is $4,320 and that's his interest rate he will have to pay for 6 years. If you want to know how much he has to pay in the total 6 years you simply just add the interest rate $4,320 to $9,000 and you get $13,320.
I hope that helped you.
Answer:
{(2, 1)}
Step-by-step explanation:
The graph shows the only solution to be the point (2, 1). Hence the solution set will be a set containing one element—that point:
{(2, 1)}
