Day 3





To Graph a System of  Inequalities

1.  Graph each inequality separately. 

2.  The solution to the system, will be the ________ where the shadings from each inequality overlap.



Use the grid below.

Graph the following  system of inequalities 












  Graph each inequality as if it was stated in "y=" form.

  If the inequality is < or >, then dotted If the inequality is < or >, then solid

  Choose a test point to determine which side of the line needs to be shaded or do it intuitively.

For the test point (0,0),

0 < 2(0)-3  False

0 (-2/3)0+2 False


Since both equations were false, shading occurred on the other side of the line, not covering the point. The solution, S, is where the two shadings overlap one another.
