What is the slope of the inequality y > 3x + 1?

• 3

• 2

• 1

• 4

Why do we draw a dotted line for the inequality y > 3x + 1?

• Because it is a greater than or less than inequality

• Because it is an equal to inequality

• Because it is a quadratic inequality

• Because it is a cubic inequality

What is the slope of the inequality y < 1/2x - 3?

• 1/2

• 2

• 3

• 1

When graphing y < 1/2x - 3, how do you determine the second point after finding the y-intercept?

• Go up 1 and over 2

• Go up 2 and over 1

Why do we shade above the line for the inequality y > 3x + 1?

• Because y is less than the line

• Because y is equal to the line

• Because y is greater than the line

• Because y is not related to the line
