Gradient Formula for Real-Life Graphs

Gradient = (y₂ − y₁) ÷ (x₂ − x₁) = change in y ÷ change in x

Always include units in your answer, taken from the axis labels:

Distance (km) ÷ Time (h) = km/h
Cost (£) ÷ Units = £ per unit
Depth (cm) ÷ Time (s) = cm/s

Practice questions for Real-Life Graphs

How do you use a conversion graph to convert a value?

1. Find your value on the known axis 2. Draw a line straight up (or across) to the graph 3. Draw a line across (or down) to the other axis 4. Read off the converted value Always use a ruler for accuracy.

Formula for speed from a distance-time graph?

Speed = gradient = (change in distance) / (change in time) Speed = (y2 - y1) / (x2 - x1) Units: always check axes — e.g. km/h, m/s, miles/minute
