Algebra

2. Graphical representation of the relationship between two numerical sets of data
8. The highest or lowest point, sometimes called maximum or minimum of a parabola.
9. y – y1 = m(x – x1), where m is the slope and (x1,y1) is the point
11. y = a(x - h)2 + k, common point to join the two line segments.
13. An unknown number represented by a letter
14. A relationship where the dependent y values decrease as independent x values increase
16. A method of solving a system of equations by adding or subtracting equations to get rid one of the variables
18. b2 – 4ac
19. the y-coordinate of a point where a line intersects the y-axis

1. ax+by=c
3. y=kx
4. A vertical line that divides a parabola into 2 congruent halves
5. No relationship between the dependent y values and independent x values
6. The line that an exponential function NEVER crosses
7. A set of y-values for which a function or relation is defined.
10. A trend line that shows the relationship between 2 sets of data most accurately
12. A method of solving a system of equations by replacing a variable with an equivalent expression
15. One input to every output
17. the x-coordinate of a point where a line intersects the x-axis
18. A set of x-values for which a function or relation is defined.
