#### Home / Interactive Lessons / Algebra / GCSE / Year 9 Term 3

The start of the lesson is used to recap calculating the gradient of linear functions.  The development phase teaches students how to calculate the gradient of parallel functions.  As learning progress they are challenged to derive the equation of linear graphs.
##### Differentiated Learning Objectives
• All students should be able to understand that parallel lines have the same gradient.
• Most students should be able to calculate the equation of a line that is parallel to another.
• Some students should be able to rearrange equations in the form ax + by + c = o to calculate the gradient of parallel lines.
