Ch. 2
| Question | Answer |
|---|---|
| Direct Variation Function | a function with a formula of the form y = kx (x is to the power of n) and k cannot equal zero and n must be greater than 0 |
| Inverse Variation Function | a function with a formula of the form y = k/x (x is to the power of n). k cannot = 0 and n must be > 0 |
| Slope | Slope is rise over run. The slope of a line must be through two points, (x1, y1) and (x2, y2). It is found by Subtracting y1 from y2 and dividing that by x2 - x1 |
| Rate of Change | The slope of a line is the rate of change of y with respect to x determined by two points on the line. |
| Mathematical Model | a mathematical model for a real situation is a description of that situation using the language and concepts of mathematics. |
| Combined Variation | When direct and inverse variations occur together, the situation is called combined variation. |
| Law of the Lever | states that to balance a given person seated on a seesaw, the distance d the other person is from the fulcrum is inversely proportional to that person's weight w. d = k/w |
| Hyperbola | The graph of every function with an equation of the form y = k/x |
