Hey there! The answer is 7x + 4y < 40
Let's first rearrange our data in a more structured way.
x represents a box of wings which has a cost of $7.00. Therefore the total cost of the boxes is 7x.
y represents a tray of nachos which has a cost of $4.00. Therefore the total cost of the trays is 4y.
The sum of the costs of trays and boxes, which is (7x + 4y) must be smaller than $40.
Now we can set up the inequality.

If you want to put this in slope intercept form, you need to get y alone. To do this, you first need to subtract x from both sides. Then, divide both sides by 3. Your work should look like this:
x + 3y = 6 ( - x both sides)
3y = -x + 6 (Divide both sides by 3)
y = - 1/3 x + 2
***** This is your new equation. This is easier to graph because it gives the slope and the y intercept. *******************************************************
x + 3y = 6 ( - x both sides)
