Revision notes
Use coordinate differences to calculate gradients and lengths, then connect straight-line equations with their geometric features.
Key ideas
- Straight lines and coordinate lengths
Connect line equations, gradients and distance with coordinate differences.
From the G2 Mathematics 2027 syllabus
- Finding the gradient of a straight line given the coordinates of two points on it
- Finding the length of a line segment given the coordinates of its end points
- Interpreting and finding the equation of a straight line graph in the form y = mx + c
- Geometric problems involving the use of coordinates
