GCSE Secondary Maths Age 13-17 - Graphs: Straight Lines and Gradients - Explained

The video tutorial explains how to analyze a graph showing volume over time. It covers finding the gradient by calculating the rise over run, interpreting the gradient as the change in volume over time, and understanding the graph's intercept, which indicates the initial volume in the container. Each part of the tutorial is associated with specific marks for correct methods and answers.

What is the formula for calculating the gradient of a graph?

How do you ensure accuracy when reading values from a graph?

Explain what the gradient of the graph represents in terms of volume and time.

At what point does the graph intersect the volume axis, and what does this point represent?

What is the significance of the intercept at V = 4 and T = 0?
