An investor has $6,000 to make a 5-year investment. At a 10% annual rate, how much more interest will the investment earn with compound interest than with a simple interest?

-1/2

Step by Step:

An easy equation to remember is y2-y1/x2-x1=slope.

In this problem,-9 is y2 and -3 is y1 so (-9)-(-3) is how you would set up the top half.

8 is x2 and -4 is x1 so 8-(-4) is how you would set up the bottom half.

Next you need to solve,so (-9)-(-3)=-6 and 8-(-4)=12.

Finally,you simplify. Both numbers can be divided by 6,so -6÷6=-1 and 12÷6=2,giving you -1/2 as your slope.
