anonymous · Answer

The given equation is linear function, y = mx + b

You know that m represents the slope of the line, based from your problem, the value of your m represents the the amount of money Joseph is spending per day. Also, the value of b in the function represents the y-intercept or the initial amount that Joseph has in his bank.

So based from this info, which one do you think is the right answer?
