🧭 Reading the Map of a Line
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.
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?
