Solving and Graphing Inequalities

Front

What indicates a solid boundary line in an inequality?

Back

The symbol has 'or equal to.'

Front

What does the inequality y < 2x + 3 represent in terms of graphing?

Back

The line would be dashed with shading below.

Front

Which inequality corresponds to a graph with a solid line and shading below?

Back

y ≤ \frac{2}{5}x + 1

Front

How do you determine the inequality that matches a given graph?

Back

Analyze the slope and y-intercept of the line and the direction of shading.

Front

When do you flip the inequality symbol while solving?

Back

When you multiply or divide both sides of the inequality by a negative number.

Front

What is the difference between a solid and dashed line in graphing inequalities?

Back

A solid line indicates 'or equal to,' while a dashed line indicates 'not equal to.'

Front

How do you graph the inequality y > -2x - 4?

Back

Draw a dashed line for y = -2x - 4 and shade above the line.

Front

What does the inequality y ≥ 3x represent in a graph?

Back

A solid line with shading above the line.

Front

What is the solution set for the inequality 2x - 3 < 5?

Back

x < 4.

Front

How do you express the solution of an inequality on a number line?

Back

Use open or closed circles to indicate whether endpoints are included or excluded.
