Question

(h) the past year, the grocery bill has ranged from $110 to $170. Suppose you were going to plot these points on a coordinate grid.
(a) What is a good scale to use for the y-axis? Explain your reasoning.
(b) What is a good interval to use for the y-axis? Explain your reasoning.
(i) Answer:

Answer 1

Since you need numbers up to 170, I guess you could go up to 200 on the y-axis.
Since your numbers range from 110 to 170, I'd use an interval of 10.

Answer 2

are you sure

Answer 3

That is what I'd do.
