You sold a box of cookies for $5. you plan to sell the remaining cookies for $.50 each.

8. write an equation in slope-intercept form that represents the total amount of money, y, you will have earned after selling x cookies.

9. identify the slope of the line.

10. identify the y-intercept of your line.

The equation for this scenario is y=5+0.5x. To identify the slope of the line, look to the variable "x", that causes the slope of the line. You do not know how many cookies are going to be sold at 50 cents a piece, so you put "x". The slope is 0.5. The y-intercept of the line is the fixed variable that you start with. In this case, it is 5, because that is what you sold the cookies at before, and that time period is done. The y-intercept is 5.

Ithink if im not mistaking b is -3 but im not a 100% sude

Im pretty sure it would be 6 purple rectangles.
