another name for the possible values of x
2. Graph
set of all points in a coordinate plane that represent all the solutions of the equation
3. intercept
when and equation is solved in the form y = mx + b, b represents the y-intercept
4. Range
in a function, the possible values for Y
5. Rise
change in y.
6. Run
change in X.
7. System
two or more linear equations with the same variables
8. Variable
a quantity that changes or the can have different values
9. Alternate Exterior Angle
These angle are on opposite sides of the transversal and are outside the other two lines
10. Alternate Interior Angles
These angles are on opposite sides of the transversal and are in between the other two lines
11. Complementay Angles
two angles whose sum is 90 degrees
12. Congruent
having the same size, shape, and measure
13. Corresponding Angles
angles that have the same relative positions in geometric figures
14. Equiangular
the property of a poly gon whose angles are all congruent
15. Equalateral
the poroperty of a polygon whose sides are all congruent
16. Parallel Lines
two lines that lie in the same plane and do not intersect
17. Perpendicular Lines
two lines that intersect at a right angle
18. Supplementary Angles
two angles whose sum is 180 degrees
19. Transversal
a line that crosses two ro more lines
20. Vertical Angles
two nonadjacent angles formed by intersecting lines or segments
changing the grouping of the numbers in a sum does not change the sum

Ex: (9+6)+2 = 9+(6+2)
22. Associative Prop of Mult
changeing the grouping of the numbers in a product does not change the product

Ex: (3x10)x4 = 3x(10x4)
in a sum, you can add the numbers in any order
24. Commutative Prop of Mult
in a product, you can multiply the numbers in any order

Ex: 8(-5) = -5(8)
25. Distributive
a(b+c) = ab + ac
