The graph which best shows the relationship between number of days and number of frozen treats sold is (C).
The best graph should have a slope of 120/1 which means that an average of 120 frozen treats is sold per day.
From the graphs displayed , only graph C has a slope value of 120/1
- (120 - 0) / (1 - 0) = 120/1
Graph A seems similar but has a slope of 1/120 has it has the data for frozen treats sold on the x - axis and the number of days on the y-axis.
Hence, the correct graph is (C).
