Students learn how to work out the equation of a straight-line graph.
Later, students consider negative and positive gradients as learning progresses.
Differentiated Learning Objectives
- All students should be able to derive the equation of a positive straight line graph in the form y = mx + c
- Most students should be able to derive the equation of a straight line graph in the form y = mx + c
- Some students should be able to derive the equation of a straight-line graph using two pairs of coordinates.
