4.4 Linear inequalities in Two Variables

What type of line is used for the inequality y>2x+1?

• Solid line

• Dashed line

• No line

In the inequality y≤−3x+4 how is the graph shaded?

• Above the line

• Below the line

• Only on the line

Which inequality represents a dashed line with shading above it?

• y≥5x+3

• y>−2x+1

• y≤4x−1

What way should you use to shade?

• Shade above the line for <.

• Test a point to determine where to shade.

• Always shade below the line.

What does the inequality y≥0 represent?

• A vertical line with shading to the right.

• A horizontal line with shading above.

• A horizontal line with shading below.

If y≤−x+6y, what is the slope of the boundary line?

• 1

• -1

• 6

Which inequality is represented by a solid line and shading above?

• y≤2x−3

• y>−x+1

• y≥4x−2

Answer explanation

It's a solid line as it has a equal or underline sign, It's shaded above as y is greater than the equation.
