2. The average cost of a motorcycle at a certain dealership over the last 8 years has ranged from $16,000
$20,500. Suppose you were going to plot these points on a coordinate grid.
(a) (2 points) What is a good scale to use for the x-axis? Explain your reasoning.
(b) (2 points) What is a good interval to use for the y-axis? Explain your reasoning.

Answer 1

A good scale for the x-axis is 1 year per unit, and a good interval for the y-axis is $1000 per unit.

Step-by-step explanation:

a) A good scale to use for the x-axis would be 1 year per unit, since the data spans 8 years. This allows for clear and concise plotting of the points on the coordinate grid.

b) A good interval to use for the y-axis would be $1000 per unit, since the data ranges from $16,000 to $20,500. This provides a reasonable and meaningful representation of the average cost of the motorcycles over the years.
