On which of the following lines does the point (7, 1) lie?

a y= 5x + 4
b y= -4x + 3
c y= -6 +8
d y= x - 10

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
