Algebra 1

2. A sum is the result of an addition.
5. the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
9. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
12. The regard that something is held to deserve; the importance, worth, or usefulness of something.
13. an algebraic expression of the sum or the difference of two terms.
14. are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane.
15. A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place.

1. function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
3. an imaginary line about which a body rotates
4. is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
6. an is a point on the y-axis, through which the slope of the line passes.
7. In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. ... In translating word problems into algebraic equations, quantities to be determined can be represented by variables.
8. Graph is a mathematical representation of a network and it describes the relationship between lines and points.
10. an algebraic expression of the sum or the difference of two terms.
11. of a function is the set of all possible inputs for the function.
