3. To draw, or plot, the points named by certain numbers or ordered pairs on a number line or coordinate plane.
5. A rate with a denominator of 1.
7. A pair of numbers used to locate a point in the coordinate plane or the solution of an equation in two variables. An ordered pair is written in the form (x-coordinate, y-coordinate).
8. The least nonzero number that is a common multiple of two or more numbers. Example: 36 is the least common multiple of 3, 9, and 12.
9. The second number in an ordered pair.
13. A plane, also called a coordinate grid or coordinate system, in which a horizontal number line and a vertical number line intersect at their zero points.
15. A comparison of two numbers by division.

1. Expressing a composite number as a product of its prime factors. Example: The prime factorization of 63 is 3 x 3 x 7.
2. Two ratios that have the same value.
3. The greatest number that is a factor of two or more numbers. Example: The greatest common factor of 30, 60, and 15 is 15.
4. The first number in an ordered pair.
6. The ratio of two measurements having different units of measure. Example: 60 miles per hour
10. A ratio or rate between the actual size of an object and the size of its model.
11. The vertical number line on a coordinate plane.
12. The horizontal number line on a coordinate plane.
14. The point (0, 0) in a coordinate plane where the x-axis and the y-axis intersect.
