1. Negative Slope
Positive Slope
0 Slope
Undefined Slope
• Negative Slope: A slope slanting downward to the left
• Positive Slope: A slope slanting upward to the right
• 0 Slope: A flat slope
• Undefined Slope: A strait up and down line
2. Definition of Slope
The steepness of the slant of the line
3. Ratio
A number over a number
4. Determine the Slope of a Line from a Graph or 2 Points
The ‘y’ value over the ‘x’ value
5. Formula
To find the slope of 2 points without a graph but just coordinates, the formula is ‘y2 – y1’divided by ‘x2 – x1’ equals the slope of the coordinates
6. Lines Horizontal/Vertical
Horizontal means flat or side-to-side, vertical means up and/or down
7. Vertical Line Test
You make a line through a slope of a graph to see is it has more than 1 output
8. Independent and Dependent Variables
:An independent variable is the ‘x’ value; A dependent variable is the ‘y’ value
9. Domain of Continuous Functions
Thedomain of a continuous function is the ‘x’ value of a continuous function graph
10. Range of Continuous Functions
The range of continuous functions is the ‘y’ value of a continuous function graph
11. Discrete and Continuous Data
Discrete data is single points of a graph, counting basically; Continuous data is a line that includes everything in between points and is basically measuring
12. Guess and Check
Make an educated guess then input your educated guess in the problem and check theproblem with your guess
13. The Undoing Method
A flow chart to visualize the variable and the problem better
14. Balancing Method
Shows what properties you used to solve the equation
15. Variable on Both Sides
This is when the variable is on both sides of the equals sign and you need totransfer it to only 1 side, you just need to do what you would do to regular,non-variable, numbers
16. No Solution/Infinitely Many Solutions
Self-Explanatory
17. Flipping the Symbol
When multiplying or dividing by a negative number you flip the sign
18. Transitive Property
: If one number equals a second number and the second number equals and a third number, the first number equals the third number A = B, B = C, A = C
19. Symmetric Property
: One variable equals another variable and the second variable equals the first variable A = B, B = A
20. Reflexive Property
A number equals itself A = A
21. Distributive Property
One number outside a parenthesis multiplies by all the numbers in the parenthesis A (B + C) = A (B) + (C)
22. Multiplicative Property
• A number times 1 over that number equals 1A x 1/A = 1 – Can be used with
• multiplication
A number plus its opposite equals 0 A + (-A) = 0 – Can be used with addition
24. Identity Property
Same as the Commutative Property but says a number plus 0 equals the number A + 0 = 0 + A – Can be used with multiplication and addition
25. Commutative Property
Same numbers on both sides of the equals sign; and in the same order away from the equals sign A + B = B + A – Can be used with multiplication and addition
26. Associative Property
All the same numbers on both sides of the equals sign; not in the same order, away from the equals sign, as the other side B + A + C = A + B + C – Can be used with multiplication and addition
27. Natural Numbers
Numbers,1+, not including decimals
28. Whole Numbers
Numbers0+, not including decimals
29. Integer
Positive and negative numbers, not including decimals
30. Rational Numbers
All numbers with a pattern and that can be written as a ratio.
31. Irrational
• Cannot be written as a ratio and does not have a pattern.
• Ex: Pi and square root of 2
32. Real numbers
All numbers
