Lesson details
Key learning points
- A relationship between two variables can be described using a rule.
- This relationship can be used to generate coordinate pairs.
- These pairs can be plotted on a graph.
- The shape of the curve made will give information about the relationship between the points.
- All the points on the curve satisfy the relationship.
Keywords
Substitute - Substitute means to put in place of another. In Algebra, substitution can be used to replace variables with values.
Common misconception
All graphs are linear and if graphs are not linear you join points with straight line segments.
Explore $$n+2, 2n$$ and $$x^2$$. \"I see $$n$$ and 2; they must be similar\" pupils think. Get them to compare numerically, then graphically.
