AS Level 2017 Mathematics Lesson 17 The Straight Line

This complete lesson will guide your students through the often perceived difficulty of using the equation of a straight line in the form y = mx +c to deduce the gradient and the intercept. There is no plotting of the lines but more an algebraic manipulation. The lesson incorporates when lines can be parallel and perpendicular and students are encouraged to think about setting one variable to zero to find where the line crosses the other axis. The resource that accompanies the lesson is fully differentiated. This lesson can be used for gifted KS3 or 4 students
