  1. What is the equation of the y-axis on a coordinate plane?

    Answer: x = 0

    Every point on the y-axis has an x-coordinate of 0, so x = 0.

  2. A line passes through (0, -2) and (4, 0). What is its slope?

    Answer: 1/2

    Slope equals (0 - (-2))/(4 - 0) = 2/4 = 1/2.

  3. Which point does NOT lie on the line y = 3x?

    Answer: (2, 5)

    For x = 2, y should be 6, so (2, 5) is not on the line.

  4. If you reflect the point (3, 5) across the x-axis, what are its new coordinates?

    Answer: (3, -5)

    Reflecting across the x-axis negates the y-coordinate, giving (3, -5).

  5. A line graph rises steeply, then levels off. What does the steep part show compared to the flat part?

    Answer: A faster rate of change

    A steeper section of a line graph indicates a faster rate of change.

  6. What is the x-intercept of the line y = 2x - 6?

    Answer: 3

    Set y = 0: 0 = 2x - 6, so x = 3.

  7. Which transformation moves a graph up without changing its slope?

    Answer: Increasing the y-intercept

    Raising the y-intercept shifts the line up while keeping the same slope.
