Hi, there--

Problem:
Conner has 25,000 in his bank account. Every month he spends $ 1,500. He does not add money to the account.

How much money will Conner have in his account after 8 months?

Answer:
You can model this situation with a linear equation in the form y=mx+b.

The y-intercept b is the starting balance in in Conner's account: $25,000.

The slope m is the amount Conner spends each month: - $1,500 per month. The slope is negative because the bank balance is decreasing.

The equation is .

The variable x represents the number of months since the account opened.
The variable y represents the monthly balance.

You want to know the balance after 8 months, so x=8. Substitute 8 for x in the equation.




Solve for y.



After 8 months, Conner's bank balance is $13,000.

That's it.
