Graphing Linear Inequalities Quiz

What is the first step in graphing a linear inequality?

• Treat the inequality as an equation of a line

• Shade the graph

• Identify the y-intercept

• Draw a dotted line

When graphing y > 2x + 1, what type of line should be used?

• Solid line

• No line

• Dashed line

• Dotted line

What does an open circle on a graph indicate?

• The line is dotted

• The line is solid

• The point is not included in the solution

• The point is included in the solution

How do you determine where to shade when graphing y > 2x + 1?

• Shade below the line
