Aretiree invests $5,000 in a savings plan that pays 4% per year. what will the account balance be at the end of the first year?

The account balance will be $1250 at the end of the first year

The coordinates for each are:
A: (5,3)
B: (-3,-3)

Now we need to find the difference between the x and y.
x= 5 --3
x=5+3
x=8

y=3--3
y=3+3
y=6

Do now let's pretend it's a right angled triangle with side length 8 and 6:
8^2+6^2=h^2 Where h is the distance between between A and B
64+36=h^2
100=h^2
sqrt 100 is 10 so h=10

Meaning the answer is A

Hope this helps :)
