  1. What is the midpoint of the segment connecting (2, 4) and (6, 8)?

    Answer: (4, 6)

    The midpoint averages coordinates: ((2+6)/2, (4+8)/2) = (4, 6).

  2. A bar graph is best used to display what kind of data?

    Answer: Comparisons across categories

    Bar graphs compare amounts across distinct categories.

  3. Which graph best shows the relationship between two numerical variables?

    Answer: Scatter plot

    A scatter plot displays paired numerical data to reveal relationships.

  4. On a line graph showing temperature over time, what does a flat horizontal section mean?

    Answer: No change in temperature

    A flat horizontal line means the value stays the same over that interval.

  5. A pie chart slice represents 25% of the total. What is the angle of that slice?

    Answer: 90 degrees

    25% of 360 degrees equals 90 degrees.

  6. Which equation represents a line that is steeper than y = 2x + 1?

    Answer: y = 5x + 1

    A larger absolute slope means a steeper line, so y = 5x + 1 is steeper.

  7. What does it mean if a scatter plot shows points trending upward from left to right?

    Answer: A positive correlation

    Points rising together indicate a positive correlation between the variables.
