Week 9: Graphing Systems of Inequalities

This week we covered Graphing Systems of Inequalities in the chapter Systems of Equations and Inequalities. 

This is simply review from Algebra from graphing the inequality and shading. 

First you will:

1. Graph each equations

     a line: y=mx+b

     a parabola: y=(x-h)^2 +k

     a circle: x^2 + y^2 = r^2

2. Pick a test point not on the line

3. Shade the plain containing the test point. If the test point satsifies the equation shade the other plane ift id does not

   ≥ or ≤ solid line

   > or < dotted line

This is how you will solve such a problem.

Below is one example of this problem.

In this problem. You can see the equations being graphed and then finding which side to shade. the place where both lines have shaded is the answer for the equation. 

That is how you graph systems of inequalities

See You Next Week!!!
