Lesson Details
Key learning points
- Real life relationships can be represented using a linear graph.
- Real life problems can be solved using a linear graph.
- Switching between algebraic and graphical representations can help solve real life problems.
Common misconception
There is one answer to everything in maths.
We often see arithmetic and equations with one answer but, maths can be used to compare and justify multiple answers to a single problem.
Keywords
Rate of change - The rate of change is how one variable changes with respect to another. If constant, there is a linear relationship.
