Day 71 – December 8

Algebra: Chapter 9, Review

Remember! IN GRAPHING SYSTEMS OF LINEAR INEQUALITIES! For the first equation, we can use any technique we learned from Chapter 7. Usually, the slope-intercept or `x` and `y` intercepts can be used to quickly define the line. Check a simple point like (0, 0) to see if that part of the ½ plane is true. If so, then shade that area.

Do the same for the other inequality and shade the appropriate ½ plane. The IMPORTANT PART is WHERE THE 2 INEQUALITIES OVERLAP THEIR SHADING, IS THE SOLUTION TO BOTH INEQUALITIES.

Have your notes organized for TOMORROW’s CHAPTER 9 TEST!
