Answer:
Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate). The origin is located at (0,0).

Answer:
The range of round 2 scores are higher than round 1 scores.
Step-by-step explanation:
Round 1:
x x
x x
x x
x x
-------------------
1 2 3 4 5
Round 2:
x x x
x x x x x
-------------------
1 2 3 4 5
The range is the difference between the highest and lowest points of the data. In this case, the range of round 1 scores is 5 - 4, or 1, while the range for round 2 scores is 5 - 1, or 4. Therefore, the range for round 2 scores are higher than the round 1 ones.
