  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
  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
  23. Additive Property
    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
