Real-life graphs
Read conversion, distance-time and cost graphs, say what the gradient and intercept mean, and solve simultaneous equations where two lines cross.
You will be able to
- Use conversion graphs, including for values off the graph
- Find speed from a distance-time graph
- Interpret the gradient and intercept in context
- Solve simultaneous equations by reading where two lines cross
