Graphing
Types of graphs, their relationship and equation

2. (if X gets larger, Y gets larger)
Types of Graphs
Linear –
1. Shape = straight line
2. Trendline name = linear
3. Equation : y = mx + b
m = slope ; b = y-intercept
(if X gets larger, Y gets larger)

3. Types of Graphs (cont.) Types of Linear Graphs:
1. Linear Relationship: Has a Y-intercept (b); doesn’t start at (0,0)
2.Direct Relationship : No Y-intercept (b); starts at (0,0)
equation becomes y = mx

4. Linear Relationship Graph
Acceleration (m/s2)
Net Force (N)

5. Direct Relationship Graph

6. (if X gets larger, then Y gets larger by the square of X)
Types of Graphs (cont.)
Quadratic –
1. Shape = parabola
2. Trendline name = polynomial
3. Equation : y = ax2 (a = constant)
(if X gets larger, then Y gets larger by the square of X)

7. Quadratic Relationship Graph

8. (as X gets larger, Y gets smaller)
Types of Graphs (cont.)
Inverse –
1. Shape = hyperbola
2. Trendline name = power series
3. Equation: y = a/x (y = ax-1)
(as X gets larger, Y gets smaller)

9. Inverse Relationship Graph
