1. Linear Equation- A equation in the form Ax+By=C, with a graph that is a straight line.
2. Standard Form- The standard form of a linear equation is Ax+By=C, where A≥0, A and B are not both zero, and A, B, and C are integers with a greatest common factor of 1.
3. Constant- A monomial that is a real number.
4. X-intercept- The x-coordinate of a point where a graph crosses the x-axis.
5. Y-intercept- The y-coordinate of a point where a graph crosses the y-axis.
3-2
6. Linear Function- A function with ordered pairs that satisfy a linear equation.
7. Parent Function- The simplest functions in a family. The simplest linear furnction is f(x)=x is called the ____________ of the family of linear functions.
8. Family of Graphs- Graphs and equations of graphs that have at least one characteristic in common.
9. Root- The solutions of a quadratic equation.
10. Zeros- The x-intercepts of the graph of a function; the points for which f(x)=0.
3-3
11. Rate of Change- How a quantity is changing with respect to a change in another quantity.
12. Slope- The ratio of the change in the y-coordinates (rise) to the corresponding change in the x coordinates (run) as you move from one point to another along the line.
3-4
13. Direct Variation- A equation of the form y=kx, where k is not equal to zero.
14. Constant of Variation- The number k in equations of the form y=kx.
15. Constant of Proportionality- Another term for constant of variation.
3-5
16. Sequence- A set of numbers in a specific order.
17. Terms of the Sequence- The numbers in a sequence.
18. Arithmetic Sequence- A numerical pattern that increases or decreases at a constant rate or value. The difference between successive terms of the sequence is constant.
19. Common Difference- The difference between the terms in an arithmetic sequence.
