Sagot :
1. Graph the system first. Make the inequality sign an equal sign so you can see.
2. If it is a "greater than" sign, shade the positive side.
3. If it is a "less than" sign, shade the negative side.
2. If it is a "greater than" sign, shade the positive side.
3. If it is a "less than" sign, shade the negative side.
*RULES IN GRAPHING INEQUALITY IN TWO VARIABLES*
❶Replace the inequality symbol by an equal sign.
❷Graph the resulting equation using any method (Graphical, Substitution & Elimination)
❸Shade half of the plane in which the coordinates of the points satisfied the original inequality
