Vocabulary Math

4. A function is a rule that assigns exactly one output to each possible input.
7. when x
8. of change: The rate of change in a linear relationship is the amount y
9. Counterclockwise means to turn opposite of the way the hands of a clock turn. The top turns to the left.
13. When part of an original figure matches up with part of a copy, we call them corresponding parts
14. the coordinate plane, because it is three units to the right and two units up.
16. cylinder is a three-dimensional figure like a prism, but with bases that are circles.
20. variable: A dependent variable represents the output of a function.
21. interior angles: Alternate interior angles are created when two parallel lines are crossed by another line called a transversal.
22. An image is the result of translations, rotations, and reflections on an object.
23. wise: Clockwise means to turn in the same direction as the hands of a clock. The top turns to the right. This diagram shows Figure A turned clockwise to make Figure B.
24. plane: The coordinate plane is a system for telling where points are. For example, point R

1. number: A rational number is a fraction or the opposite of a fraction.
2. A dilation is a transformation in which each point on a figure moves along a line and changes its distance from a fixed point
3. by 1.The rate of change in a linear relationship is also the slope of its graph.
5. They tell you how many factors to multiply
6. of dilation: The center of a dilation is a fixed point on a plane. It is the starting point from which we measure distances in a dilation.
10. A cone is a three-dimensional figure like a pyramid, but the base is a circle.
11. variable: An independent variable represents the input of a function.
12. One figure is congruent to another if it can be moved with translations, rotations, and reflections to fit exactly over the other.
15. of proportionality: In a proportional relationship, the values for one quantity are each multiplied by the same number to get the values for the other quantity.
17. relationship: A linear relationship between two quantities means they are related like this: When one quantity changes by a certain amount, the other quantity always changes by a set amount.
18. A radius is a line segment that goes from the center to the edge of a circle. A radius can go in any direction. Every radius of the circle is the same length. We also use the word radius to mean the length of this segment.
19. number: An irrational number is a number that is not a fraction or the opposite of a fraction.
