(Algebra II) The equation Suppose y = 12 + 10 x models the amount of money in your wallet, where y is the total in dollars and x is the number of weeks from today. If you graphed this equation, determine what the slope represents in the situation.
A). Slope represents the amount of money with which you are beginning.
B). The slope represents the amount of money you are adding to your wallet each week.
C).The slope represents the total amount of weeks that you collect money.
D).The slope represents the total amount of money in your wallet after x weeks.
point-slope form: y=mx+b m=slope b=y-intercept In this function: y=12+10x ⇒y=10x+12; the slope is : m=10.
In this function: y=10x+12; b=12 is the amount of money with which you are beginning. m=10 represents the amount of money you are adding to your wallet each week.
Answer: B) the slope represents the amount of money you are adding to your wallet each week.
