The first day of my solving systems by substitution lesson, I see so many heads explode. The slope is -1, so go down one unit and over one unit and draw a point. Solve the given system of equations by graphing. We've found a system of equations: The problem asks how many items sold will give Tammy and Lisa the same amount of money, so we want to find x when the y-values on the two lines are the same. So first, in the red equation, I want to see if my y number is equal to my x number plus 4.

Graph your amount, Y, on the y-axis and your friend's amount, F, on the x-axis it actually doesn't matter which is which as long as you label them correctly. This point works in the first equation. Sample Problem Tammy and Lisa work in retail, in different shops. Why did one line cross the other line? Three times as many student tickets were sold compared to adult tickets.
