Algebra

6. Graphical representation of the relationship between two numerical sets of data
11. A relationship where the dependent y values decrease as independent x values increase
12. A method of solving a system of equations by adding or subtracting equations to get rid one of the variables
13. A method of solving a system of equations by replacing a variable with an equivalent expression
15. One input to every output
17. y – y1 = m(x – x1), where m is the slope and (x1,y1) is the point
19. No relationship between the dependent y values and independent x values

1. the y-coordinate of a point where a line intersects the y-axis
2. The highest or lowest point, sometimes called maximum or minimum of a parabola.
3. the x-coordinate of a point where a line intersects the x-axis
4. A set of y-values for which a function or relation is defined.
5. The line that an exponential function NEVER crosses
7. A trend line that shows the relationship between 2 sets of data most accurately
8. b2 – 4ac
9. An unknown number represented by a letter
10. y=kx
13. ax+by=c
14. y = a(x - h)2 + k, common point to join the two line segments.
16. A vertical line that divides a parabola into 2 congruent halves
18. A set of x-values for which a function or relation is defined.
