Graphing Linear Inequalities Concepts

Shade the entire graph.

Solve the inequalities algebraically.

Graph each inequality separately.

Find the intersection of the inequalities.

To eliminate variables.

To change the solution set.

To simplify the graphing process.

To make them more complex.

Plotting points.

Using fractions.

Complex calculations.

Using a calculator.

Set x to 0 and solve for y.

Solve the equation directly.

Set y to 0 and solve for x.

Set both x and y to 0.

No line.

Solid line.

Dashed line.

Dotted line.

To make it more difficult.

To easily identify the slope and y-intercept.

To eliminate the x variable.

To change the inequality symbol.

-3

3

3/4

-3/4

The inequality does not include the boundary line.

The inequality is equal to zero.

The inequality is undefined.

The inequality includes the boundary line.

(2,2)

(0,0)

(-1,-1)

(1,1)

The point is on the boundary line.

The region containing the point is not part of the solution.

The point is a solution to the inequality.

The inequality needs to be rewritten.
