Graphing Linear Inequalities Notes
To graph a linear inequality, we need to know the slope and y-intercept. If the
inequality does not have y by itself, you need to rewrite it.
The rules for graphing inequalities are as follows (once y is by itself!):
If your inequality has a >, you will draw a ___________ line and shade _____________.
If your inequality has a ≥, you will draw a ___________ line and shade _____________.
If your inequality has a <, you will draw a ___________ line and shade _____________.
If your inequality has a ≤, you will draw a ___________ line and shade _____________.
Graphing Systems of Linear Inequalities
Solutions for a system of inequalities must make BOTH inequalities true.
Is (-3, -1) a solution to {𝑦 > 2𝑥 − 53𝑥 − 4𝑦 ≤ 9
