  1. What is the slope of a horizontal line?

    Answer: 0

    A horizontal line has no vertical change (rise = 0), so slope = rise/run = 0.

  2. The midpoint of a segment with endpoints (2, 4) and (8, 10) is:

    Answer: (5, 7)

    Midpoint = ((2+8)/2, (4+10)/2) = (10/2, 14/2) = (5, 7).

  3. Two vertical angles are formed when two lines intersect. If one angle measures 65°, the vertical angle measures:

    Answer: 65°

    Vertical angles are always congruent, so both measure 65°.

  4. What is the distance between the points (0, 0) and (3, 4)?

    Answer: 5

    Distance = √(3² + 4²) = √(9 + 16) = √25 = 5.

  5. A circle has the equation x² + y² = 25. What is its radius?

    Answer: 5

    In the standard form x² + y² = r², we have r² = 25, so r = √25 = 5.

  6. Which statement is true about a rectangle?

    Answer: Opposite sides are parallel and equal in length

    A rectangle has opposite sides that are both parallel and equal, with all four angles measuring 90°.

  7. Point A is at (1, 2) and point B is at (7, 10). What is the length of segment AB?

    Answer: 10

    Length = √((7−1)² + (10−2)²) = √(36 + 64) = √100 = 10.
