Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

1 Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.

2 Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences. Write the equation in function notation.

3 Explain what the graph of the function represents. Be sure to use complete sentences. Graph the function. On the graph, make sure to label the intercepts.

4 You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.

5 Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
