**Henry**, Wednesday, July 27, 2011 at 4:05pmGraphing Linear Inequalities

1. Graph the boundary line. This is done by using an equal sign instead of

the inequality sign. The boundary line

is a dotted line if there's no equal sign in the inequality.

2. Shade the area that contains the solution. The solution is all points

above or below the boundary line. If

your inequality is y > 2x-4, the solution is above(>)the. If the inequality is y < 2x-4, the solution

is below(<) the line. Choose any point (x,y)in the shaded area and it will

satisfy your inequality. If you have a solid boundary line,y =< 2x-4, all

points on the boundary line should also satisfy the inequality.

I hope this will help.
