Gradient and Midpoint of Line Segments

Students learn how to calculate the gradient and midpoint of line segments. Later, as learning progresses students work out the equation of a line that runs equidistant between two points.

Recapping Equation of Straight Line Graphs

At the start of the lesson students recap how to write the equation of straight line graphs in the form y = mx + c and ax + by + c = 0.

Gradient and Midpoint of Line Segments

In the development phase, students learn how to work out the midpoint and gradient of a line segment. Later, as learning progresses coordinate pairs are given as unknowns.

Challenge Question

In the plenary, students are challenged to use the gradient and midpoint of a line segment to find the equation of a perpendicular bisector between two coordinate pairs.
