Students learn about interpreting straight line graphs by finding the gradient and intercept values.
As learning progresses they find the equation of linear graphs with negative and fractional gradients and intercepts.
Differentiated Learning Objectives
- All students should be able to find the gradient of a straight-line graph with an intercept of zero.
- Most students should be able to find the gradient and intercept of a straight-line graph.
- Some students should be able to calculate and interpret gradients and intercepts of graphs of linear equations.
