What is the slope of a line passing through the points (-2, -3) and (6, 9)?

• 3/2

• 3

• 2/3

• 1/2

How do you find the x-intercept of the equation 2x - 3y = 6?

• Set x to 0 and solve for y

• Set y to 0 and solve for x

• Multiply both sides by 3

• Divide both sides by 2

How do you solve the inequality 5x - 11 ≥ 9?

• Add 11 to both sides, then divide by 5

• Subtract 11 from both sides, then multiply by 5

• Multiply both sides by 5, then add 11

• Divide both sides by 5, then subtract 11

What are the solutions to the absolute value equation |3x + 4| = 9?

• x = 4 or x = -4

• x = 9 or x = -9

• x = 3 or x = -3

• x = 5/3 or x = -13/3
