Graphing Inequalities in Slope-Intercept

What is a Linear Equation?

An equation whose graph is a line.

Review of Graphing Linear Inequalities

• Change to Slope-Intercept Form if needed (Get y by itself).

• Plot y intercept and use the slope to find the second point.

• Determine if dashed or solid line (< , > is dashed and < , > is solid).

• Determine whether to shade above or below ( > shade above, < shade below).
