Graphing Inequalities and Systems

Algebra scholars...greetings! What you are witnessing in this post is a system with inequalities rather than equalities. Remember, the only differences are that if you have a 'less than' or 'greater than' sign, the line is dashed rather than a solid line.

Also, don't forget to shade. Always look at the direction of the inequality symbol. Shade where number get larger (greater than) or where the numbers get smaller (less than).

So what about the solution????? Instead of only where the lines intersect, it is where the shading overlaps.

Good luck.
