  1. A coordinate is written as (?, y), where the first value represents the horizontal position.

    Show answer

    x

  2. A coordinate is written as (x, ?), where the second value represents the vertical position.

    Show answer

    y

  3. What are the coordinates of the origin on a coordinate grid?

    Show answer

    (0, 0)

  4. What sign (positive or negative) do x-coordinates have in the left half of a coordinate plane?

    Show answer

    Negative. Points to the left of the y-axis have negative x-coordinates.

  5. What sign (positive or negative) do y-coordinates have below the x-axis?

    Show answer

    Negative. Points below the x-axis have negative y-coordinates.

  6. What is the formula for the x-coordinate of the midpoint between points (x₁, y₁) and (x₂, y₂)?

    Show answer

    (x₁ + x₂) / 2

  7. What is the midpoint between A(2, 9) and B(10, 1)?

    Show answer

    (6, 5). Calculate ((2+10)/2, (9+1)/2) = (12/2, 10/2) = (6, 5).

  8. What is the midpoint between C(5, 14) and D(11, 4)?

    Show answer

    (8, 9). Calculate ((5+11)/2, (14+4)/2) = (16/2, 18/2) = (8, 9).

  9. What is the midpoint between A(−8, 3) and B(−2, 19)?

    Show answer

    (−5, 11). Calculate ((−8+(−2))/2, (3+19)/2) = (−10/2, 22/2) = (−5, 11).
