Algebra 1 Terms

4. value: The distance number is from 0.
7. A constant that a variable or expression is multiplied by.
9. term: A term that is a constant. For a polynomial in x, it’s the term without an x.
11. plane: A 2-dimensional flat surface used for plotting points, lines, curves, and regions. It contains an x and a y axis which intersect at the origin.
13. like terms: Using the distributive law to add any two multiples of an expression such as x.
14. of symmetry: A line that you can flip (or reflect) a graph across that results in the same graph.

1. The study of mathematical symbols and the rules for manipulating those symbols.
2. A mathematical sentence with an equals sign (like 3x+5=11).
3. A single fixed number (unlike a variable, whose value can vary).
5. Using exponents, especially using variables in exponents.
6. The distance between two quantities, or the answer to a subtraction problem.
8. coefficient: A constant term, thought of as a coefficient of 1.
9. difference: In an arithmetic sequence, the amount that can be added to each number to get the next one.
10. The set of inputs (x-coordinates) of a relation or function.
12. A fractional quantity written with a decimal point (like 0.5).
