When graphing a linear inequality what determines the dotted line?

• the time of the day

• the number of terms in the inequality

• the sign of the inequality

• whether x is positive or negative

Write a system of linear inequalities that matches the graph?

• $y\le\frac{2}{3}x+3$
  $y>-\frac{2}{3}x-1$

• $y\ge\frac{2}{3}x-3$
  $y<\frac{2}{3}x+1$
  

• $y\ge\frac{2}{3}x-1$
