Question

The graph below shows the relation between the number of minutes and the price charged by the cell phone service provider. Which of the following coordinates are needed to find the unit rate?

• A. (3, 0.9), (6, 1.8)
• B. (0.9, 3), (1.8, 6)
• C. (5, 1.2), (6, 1.5)
• D. (8, 2.4), (4, 1.2)

Answer 1

The correct option is A (3, 0.9), (6, 1.8)

To find unit rate, we have to take two points (3,0.9) and (6,1.8).

Hence, the coodinates (3,0.9) and (6,1.8) are needed to find the unit rate.
