Scaled trace inequality
WebSince you know x always equal 1, then you get the two points (1,2) and (1,3). If you graph the line through these two points, You will see that you get the vertical line going through the point (1,0). So now since the inequality is > and not greater than or equal to, you use a dashed vertical line.
