Something in Common 25: Crossed Lines

Earliest recommended Year group: Year 11.

This tests the pupils knowledge of straight line graphs and y=mx+c and the significance of gradients of perpendicular lines.

This is from the “Something in Common” collection of resources by John Burke. They allow consolidation of key skills, prevent students from copying each other (as all the questions are different), make marking and assessing easy for the teacher (as all the answers are the same!), and provide a lovely extra challenge for students as they try to figure out exactly what is going on!
