Linear Inequality Graphing Solutions with Two Variables

When graphing an inequality, why make a dashed boundary line?

• to show the solutions on the boundary

• to break up the equal and not equal parts

• to show that the points on the line are not solutions

• to show that its an inequality not an equation

What does the shading represent on the graph of this linear inequality?

• the points that are also solutions in addition to the points on the line

• the points that are not included as solutions

• the solutions that sometimes make the inequality true

• the coordinate pairs that would not make the inequality true

• dashed horizontal line at 5, shading below

• dashed vertical line at 5, shading to the left

• solid vertical line at 5, shading to the left

• dashed horizontal line at 5, shading to the left

Which point below is NOT part of the solution set?

• (0, 0)

• (-10, 20)

• (3, 5)

• (0, -2)

Which point below is NOT part of the solution set?

• (0, 0)
