Steps to Graphing Linear Inequalities in slope – intercept form:
1. Identify the y – intercept (b)
2. Identify the slope (m)
3. Determine whether you need a dashed or solid line
a. Dashed line for < or >
b. Solid line for ≤ or ≥
4. Shade above or below the line
a. Above if y is > or ≥
b. Below if y is < or ≤
