- 4. A measure of the steepness of a line
- 5. The y-coordinate of the point where a line crosses the y-axis.
- 7. A pairing between two sets of numbers
- 10. A pairing between two sets of numbers in which each element of the first set is paired with no more than one element of the second set
- 12. root f(x)=√x
- 14. Function An equation whose graph in a coordinate plane is a straight line
- 16. variable a variable (often denoted by x ) whose variation does not depend on that of another.

Down
- 1. form A linear equation written in the form y = mx + b where m is the slope and b is the y-intercept of the equation's graph
- 2. The first coordinates in a set of ordered pairs of a relation or function
- 3. Where function is below x-axis
- 6. Where the function is above the x-axis
- 8. behavior This describes what happens to the function as x increases and decreases.
- 9. form A linear equation written in the form y - y₁ = m(x - x₁), where the coordinates x₁ and y₁ are taken from a given point, (x₁, y₁), and m is the slope.
- 11. function Set of basic functions from which related functions are derived by transformations
- 12. Form of a linear equation A linear equation written in the form Ax + By = C, where A, B, and C are real numbers, A and B are not both zero, and A is not negative.
- 13. of Change A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable.
- 15. Nation A method of writing a function in which the dependent variable is written in the form f(x). The independent variable,x,is placed inside the parentheses
- 17. lines. Two different lines that have the same slope.
