Solving and Graphing Linear Inequalities August 28,2012

Linear Inequalities  The solution to a linear inequality is a shaded region of the coordinate plane and is called a half-plane bounded by a boundary line.

Ex. ½ Is the ordered pair a solution of the inequality? 

 Ex.1 Graph.

 Ex.2 Graph.

 Ex.3 Graph.

 Ex.4 Graph.

 Ex.5 Write the Inequality

 Ex.6 Write the Inequality

Ex.7 Practice with Word Problems  The dairy association is thinking of opening a milkshake stand at the fair. A goal of making a profit of over $800 makes it worthwhile to open.  A. If they sell 400 small shakes, x, and 250 large shakes, y, write an inequality representing the profit they would have to make on each size to reach at least a profit of $800.
