Graphs

Lines
1. y = mx + c
  1. Linear Graphs
  2. C
    1. The Intercept
    2. Where it crosses the Y axis
  3. M
    1. Gradient
  4. Y
    1. The Y axis coordinate
    2. (X,Y)
  5. X
    1. The X axis coordinate
    2. (X,Y)
2. Highest number of x's tells us what type of graph it is
3. y = 3x3 + 4x2 + 8
  1. The x3 is larger than x2
    1. Therefore it is a cubic graph not a quadratic graph
Gradients
1. M
2. The higher the gradient the steeper the line
3. The smaller the gradient the shallower the line
Graphs
1. Reciprocal
  1. y = n/x
    1. n = number
  2. Break in the graph
  3. Positive are in the 1st and 3rd quadrants
  4. Negative are in 2nd and 4th quadrants
2. Cubic
  1. y = x3
  2. Positive are from the bottom left corner
  3. Negative are from the top left
  4. S shaped
3. Quadratic
  1. y = x2
  2. U shaped
  3. Positive are u shaped
  4. Negative are n shaped
4. Linear
  1. Straight Line
  2. Positive
    1. Upwards sloping Gradient
      1. Bottom to Top
  3. Negative
    1. Downward sloping Gradients
      1. Top to Bottom
  4. y = mx + c
