Every straight line has two crucial pieces of information written into its DNA - its gradient (how steep it climbs) and its intercepts (where it meets the axes). These are like the coordinates on a treasure map, telling you exactly where you are and which direction you're heading!
Mastering gradients and intercepts gives you the power to decode any linear relationship.
This introduction covers Reading the Map of a Line within Gradient & Intercept for GCSE Mathematics. Revise Gradient & Intercept in Graphs for GCSE Mathematics with 10 exam-style questions and 20 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 1 of 9 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
Practice questions for Gradient & Intercept
The gradient of a straight line is calculated by:
A graph shows the distance (km) travelled by a car plotted against time (hours). The line has gradient 80. What does the gradient represent in this context?
