Equations of Parallel Lines

MA15-07

This lesson is coming soon.

In this lesson

Identify whether lines are parallel by comparing their gradients in y = mx + c form, and find the equation of a line parallel to a given line through a stated point.

What it covers

  • Identifying which lines are parallel by comparing the gradient (m) in y = mx + c form, ignoring the intercept
  • Finding the equation of a line parallel to a given line, through a stated point: keep the gradient, find a new c

Key words

For: AQA GCSE 8300, Edexcel GCSE 1MA1, Eduqas GCSE C300, OCR GCSE J560, Edexcel IGCSE 4MA1, Cambridge IGCSE 0580

For teachers

This GCSE Maths lesson teaches equations of parallel lines. By the end, students should be able to identify whether lines are parallel by comparing their gradients in y = mx + c form, and find the equation of a line parallel to a given line through a stated point. It works through two worked examples and the mistakes examiners report.
