A family is tracking its spending habits. Over the past year, the grocery bill has ranged from $110 to $170. Suppose you were going to plot theses points on a coordinated 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.
You would plot them by each month, 170-110= 60 dollar increase. 60 divided by 12, that leaves a 5 dollar increase each month. Your coordinates would be (0,110) (1,115) (2,120) (3,125) The x would be the month The y would be the money
