Graphing Inequalities Concepts

Find the x-intercept

Solve the inequality

Shade the graph

Determine the type of line to use

Because it is a horizontal line

Because it is a vertical line

Because it does not include points on the line

Because it includes points on the line

To find points to plot on the graph

To solve the inequality

To shade the graph

To determine the type of line

Use a solid line

Shade below the line

Use a dotted line

Shade above the line

y ≥ 2x - 2

x > -2

y < x + 3

y ≤ 2

It shows which side of the line is the solution

It is not important

It helps find the intercepts

It determines the type of line to use

For 'less than or equal to' or 'greater than or equal to' symbols

For 'less than' or 'greater than' symbols

For vertical lines only

For horizontal lines only

The line is not part of the solution

The line is part of the solution

The inequality is unsolvable

The inequality is linear

It means the line is solid

It means the line is dotted

It means the inequality is strict

It means the inequality is non-linear

The line is part of the solution

The line is not part of the solution

The inequality is cubic

The inequality is quadratic
