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. § § .
