Exemplars (from the NaCCA curriculum)

E.g.1 Draw graphs for real life problems.
i. Every morning, you go for a walk. The distance you walk can be modelled by the equation d = 1 h,where d is the distance walked in kilometers and h is the number 3
of hours you've walked. Make a table for the relation and draw a graph with the values to see how far you've walked after 6hours.

Copy and complete the table for the relation: Distanc 1 2 3 4 5 e Time
E.g.2 Nhyira paints portraits of people for a living. The graph below shows how much she charges based on how long it takes her to paint the portrait. Use the graph to answer the questions that follow.

i. How much does she charge for a portrait that takes 3 hours to paint?
ii. Is she charges GH₵175, how many hours did she use to paint the portrait?
iii. How many hours will she require to paint a portrait that cost GH₵300?
