Can someone help me with linear functions? 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.

    Is this already right? 1. 2x + 3y = 1,470 –2x –2x 3y = –2x + 1,470 3y/ 3 = –2x/3 + 1,470/3 y = –2x/3 + 490 The y-intercept of this equation is 490 and the slope is -2x/3. 2. I would graph this line by finding the y-intercept 490 first. Then, you would move down twice from 490 to 488. Finally, you would move to the right 3 times. 3. F(x) = –2x/3 + 490 The graph would represent the profit of Sal’s Sandwich Shop on every sandwich and wrap from the lunch specials last month. 4.

    I fail to see what the problem is or expectation is from your opening statement.
