Mathematics 1.2 Sketch and interpret graphs
Key tips
- Use a ruler for drawing line graphs.
- Look carefully at the scales on each axis. When working out the gradient do not simply count squares – remember to check how many units each grid line represents first.
- Answer the question in the context that is given. Use commonsense to check your answer.
- Know the difference between ‘intercept’ and ‘intersect’. An intercept is a point where the graph crosses the axes. Intersect means cross or meet.
- Parabolas should be smooth curves with a rounded turning point (vertex).
- Show your working clearly in correct mathematical steps. Give a full sentence stating your answer.
- Show all working as credit may be given for a minor slip, if the assessor can see what you have done.
- Reread the question to check that you have answered the question asked.
- You may be asked to form equations of linear graphs within a context for Achievement with Merit, and for quadratic graphs for Achievement with Excellence.
- Attempt all questions as evidence from higher level questions may be used in awarding credit for a lower grade.
