An initial investment of 480$ is appreciated for 2 years in an account that earns 7% interest, compound quarterly. Find the amount of money in the account at the end of the period.

C

Step-by-step explanation:

The x-intercept is found when y=0, and the y-intercept is found when x=0.  If y=0, then we have:

2x=24

x=12

Therefore, the x-intercept is 12, so the full coordinates are (12, 0).  Note that the only option with this x-intercept is C, so C is the correct answer.

You can find the y-intercept similarly.  If x is zero, then:

-6y=24

y=-4

Therefore, (0, -4) is the y-intercept.
