Graphing+Inequalities

=Graphing 2 Variable Inequalities(Chapter 6.7):= Austin, The Katie, Molly H.

__Graphing Inequalities__  
 * While graphing inequalities, treat ≤ , ≥, <, and > the same as an equal sign.
 * When putting the points on the graph the equations that have ≤ or ≥ in them should be represented by a solid line. When graphing inequalities that contain > or < the line should be dotted.
 * Once the line is drawn, the graph should now be separated into two sections: the part that can satisfy the inequality and the side that can't. To figure out which side is which, pick a point on either side of the graph, as long as it's not on the graphed line.
 * Plug it in to the equation, and then see if it is a solution.
 * To tell if the ordered pair worked as a solution, see if the number is the same on both sides of the inequality. If they are, shade in the side of the graph that that point was on to show that all the points on that side will work in the inequality. If the numbers on both sides of the inequality don't match up, that means the point you have chosen is not a solution, and the other side of the line should be shaded.
 * The ordered pair (0,0) is usually the best point to choose when testing inequalities.
