Algebraic Graphical Numerical y=ax+b
(where a and b are real numbers)
- Straight Line
- One y-intercept at (o , b)
- One x-intercept at (-b/a , o )
- Monotonically Increasing or Decreasing
- As x increases, y increases (+a) or decreases (-a) at a constant rate of "a"
- 1st differences = a
- 2nd differences = 0
