2. The distance between two quantities, or the answer to a subtraction problem
5. A number used to describe or summarize data.
7. The answer to a multiplication problem.
8. An angle that measures less than 90°.
9. In a right triangle, the side opposite the right angle.
11. The point on a coordinate plane where the x-axis and y-axis intersect.
14. The distance around an entire figure, such as a circle or a sphere. For a sphere, this means the distance around a circle on the sphere whose center is at the center of the sphere
15. The distance a number is from 0 .
16. For equations, two or more equations that are all required to be true.
18. A straight line, or an equation or expression whose graph is a straight line.
19. Using the distributive law to add any two multiples of an expression such as x.

1. When the points on a grid are not all on a straight line, but seem to have a somewhat linear pattern, you can find a line that is the “best fit” (closest) to the points.
3. Two variables in a scatter plot have a nonlinear association if the points form a pattern which is not close to a straight line.
4. A rule that assigns to each input exactly one output.
5. A number that measures how steep a line is.
6. Two lines in a plane are parallel if they always have the same distance between them, so they never intersect. If two lines are parallel, they have the same slope.
10. The answer to a multiplication problem.
12. A number that cannot be written as a fraction mn where m and n are integers.
13. The size of a region in the plane, measured in unit squares
17. All solutions to an equation or system.
