Rectangular Callout: Strategies for  Graphing Linear Inequalities.
	Graph the corresponding linear equation   ax+by=c.
	Test one point either above or below the line to see if it satisfies the given inequality..
	If the test point works, then all the points in that region will satisfy the inequality. Shade this region.
	If the test point does not work, then all the points on the other side of the line will satisfy the inequality. Shade this region.
