Linear function models quiz: 10 questions
Remember
- Rate of change \(m = \frac{\text{change in } y}{\text{change in } x}\); initial value \(b\) is \(y\) when \(x = 0\).
- Build a model: find \(m\), solve for \(b\) with one point, write \(y = mx + b\).
- A negative rate means the quantity decreases.
- A flat segment has rate 0; a curve means the rate is not constant.
- Always say what \(m\) and \(b\) mean in the situation, with units.
