7-8 Graphing Inequalities in 2 Variables
*** treat like equations
I can...
*graph an equality on a coordinate plane
Steps:
1) Solve for y.
2) Graph the line.
3) Shade - Choose a test point and test it!
Remember:
LESS THAN or GREATER THAN is a dashed line Less than/equal to; or greater than/equal to; is a solid line

7.3 Solving More Inequalities
I can...
*solve an inequality with variables on both sides
*find a solution set given a replacement set
Review from Chapter 5
To solve, with variables on both sides:
1) Simplify (distribute, exponents, like terms)
2) Get variable terms on one side
3) SOLVE!
Replacement Set: A set of numbers from which values for the variable may be chosen.
*Simply limiting our choices.

7.1-7.2 Solving Inequalities
I can...
*solve an equality using +, -, x, /
*graph solutions on a number line
*give solutions using Set-builder notation
Properties of Inequalities
1) You can add or subtract the same number from both sides.
2) You can multiply or divide by the same POSITIVE number on both sides.
#) You can multiply or divide by the same NEGATIVE number on both sides AND change the direction of the symbol.
