  1. What is the equation of a line with slope 3 and y-intercept −2?

    Answer: y = 3x − 2

    Using slope-intercept form y = mx + b: y = 3x − 2.

  2. Which of the following best describes a proportional relationship?

    Answer: y = 3x

    y = 3x passes through the origin and has a constant ratio, indicating a proportional relationship.

  3. If a right triangle has legs of 6 and 8, what is the length of the hypotenuse?

    Answer: 10

    c = √(6² + 8²) = √(36 + 64) = √100 = 10.

  4. A scatter plot shows a positive correlation. What does this mean?

    Answer: As x increases, y increases

    A positive correlation means that as the x-values increase, the y-values also tend to increase.

  5. What is the surface area of a cube with side length 4 cm?

    Answer: 96 sq cm

    Surface area of a cube = 6 × side² = 6 × 16 = 96 square centimeters.

  6. Evaluate: 2³ + 3²

    Answer: 17

    2³ = 8 and 3² = 9, so 8 + 9 = 17.
