David and James are running a lemonade stand together. They notice that for every additional cup of lemonade they sell, their profit increases. They also have a starting amount of money they make each day just from setting up the stand. In this context, explain what the slope and Y-intercept mean.

• The slope represents the maximum profit David and James can make and the y-intercept represents the minimum profit.

• The slope represents the rate of change in David and James' profit for each additional cup of lemonade sold and the y-intercept represents the starting profit they make each day from setting up the stand.

• The slope represents the profit from each cup of lemonade and the y-intercept represents the number of cups sold.

• The slope represents the ending profit David and James make and the y-intercept represents the rate of change in profit.
