On March 1, you borrow $339,000 to buy a house. The mortgage rate is 6.75 percent APR compounded semi-annually. The loan is to be repaid in equal monthly payments over 20 years. The first payment is due on April 1. How much of the third payment applies to the principal balance [Hint: You need to make an amortization table up to 4 periods]?

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
