GCSE Maths (9 - 1) Straight Line Graphs

A full lesson Powerpoint I created which covers the following topics:

  • Understanding y = mx + c
  • Finding the gradient and y-intercept from a given line
  • Finding the gradient between two points
  • Finding the midpoint between two points
  • Finding the equation of a straight line
  • Finding the coordinates of intersection points
  • Forming the equation of a straight line when given a point of intersection
  • Finding the distance between two points
  • Completing a table of values to plot a straight line
  • Understanding how Parallel and Perpendicular lines are related
  • Proving two lines are Parallel
  • Proving two lines are Perpendicular
  • Generating equations of Parallel or Perpendicular lines

The powerpoint includes tasks for students to complete in class. I have included these tasks as separate pdfs for printing convenience.
Answers are included in the powerpoint.
