Reading line information

In y=mx+cy=mx+cy=mx+c, mmm is the gradient and ccc is the y-intercept. The line crosses the y-axis at (0,c)(0,c)(0,c), so you can often read one point straight from the equation.

Perpendicular Lines and the equation of a tangent Lesson

  1. GCSE
  2. /Maths
  3. /Perpendicular Lines and the equation of a tangent

Step-by-step lessons covering AQA GCSE Maths Perpendicular Lines and the equation of a tangent for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build fluency with number, ratio and algebra first, since geometry, probability and statistics topics rely on them, and leave extra time nearer the exam for Higher-tier problem-solving and multi-step reasoning questions.
