Graphing Linear Inequalities in Two Variables

How do you represent x > 3 on a graph?

• A solid vertical line at x = 3, shading to the right

• A dashed vertical line at x = 3, shading to the right

• A solid vertical line at x = 3, shading to the left

• A dashed vertical line at x = 3, shading to the left

What type of line is used to represent x ≤ -2?

• A solid horizontal line

• A dashed horizontal line

• A solid vertical line

• A dashed vertical line

Where do you shade for the inequality y > -4?

• To the left of the vertical line at y = -4

• To the right of the vertical line at y = -4

• Above the horizontal line at y = -4

• Below the horizontal line at y = -4

How do you graph y ≤ 2?

• A dashed horizontal line at y = 2, shading below

• A solid horizontal line at y = 2, shading below

• A dashed horizontal line at y = 2, shading above

• 1

• -2

• 2

Where do you shade for the inequality y > x - 2?

• Above the line

• To the left of the line

• Below the line
