Answer: a) What is a good scale to use for the y axis? -20 units.
(b) What is a good interval to use for the y axis?- 20 units
Step-by-step explanation:
A family is tracking its spending habits. Over the
past year, the grocery bill has ranged from $120 to $180.
We need to plot these points on a coordinate grid.
If we plot the grocery bills along the y-axis, and past years will be plotted along the x-axis.
So, a) Good scale to use for the y-axis will be
1 scale = 20 units
As 120 and 180 are both divisible by 20.
So, it will be a good scale to use for the y-axis.
b) Good interval to use for the y-axis:
It will be again of 20 units.

The value of 3centimeters to kilometers is 0,00003 km
<h3>Converting centimeters to meters</h3>
In order to convert centimeters to kilometers, we will use the conversion factor below.
100cm = 1m
1000m = 1km
Given 3cm
3cm = 3/100 m
3cm = 0.03m
Convert to km
Since 1000m = 1km
0.03m = 0.03/1000
0.03m = 0.00003km
Therefore the value of 3centimeters to kilometers is 0,00003 km
