Algebra

4. A set of x-values for which a function or relation is defined.
7. A relationship where the dependent y values decrease as independent x values increase
10. A method of solving a system of equations by adding or subtracting equations to get rid one of the variables
11. y – y1 = m(x – x1), where m is the slope and (x1,y1) is the point
14. A method of solving a system of equations by replacing a variable with an equivalent expression
18. ax+by=c
19. the y-coordinate of a point where a line intersects the y-axis
20. The line that an exponential function NEVER crosses

1. No relationship between the dependent y values and independent x values
2. A trend line that shows the relationship between 2 sets of data most accurately
3. An unknown number represented by a letter
5. The highest or lowest point, sometimes called maximum or minimum of a parabola.
6. y=kx
8. A set of y-values for which a function or relation is defined.
9. A vertical line that divides a parabola into 2 congruent halves
12. b2 – 4ac
13. the x-coordinate of a point where a line intersects the x-axis
15. Graphical representation of the relationship between two numerical sets of data
16. One input to every output
