Hello!
See options in attachment.
• Atlanta (A) had a decrease of 0.25 inches from the prior year.
• Louisville (L) was 1.5 inches higher than the prior year.
• Denver (D) had 2.1 inches less than the prior year.
Which number line best represents the changes in rainfall for each city?
Consider that the number lines represents the "change in rainfall":
These lines are all centered in "zero", which represents that there was no change in the amount of water that rained compared to the previous year.
Starting from "zero", the positive values to the right indicate the increase in rainfall compared to the previous year.
Left from "zero" are the negatives numbers, these indicate the decrease in rainfall compared to the previous year.
So the "negative" sign will represent the decrease of rainfall and the "positive" sign will represent the increase in rainfall.
Jessica observed that there was a decrease of rainfall in Atlanta, so the registered value will be negative: A: "-0.25 inches" and you'll find it to the left of the number line.
For Louisville there was an increase in rainfall so it will be positive L: "+1.5 inches" and you'll find it at the right of the number line.
For Denver there was less rain, meaning, she registered a decrease in the rainfall, so it will be negative and you'll find it to the left of the number line D:"-2.1 inches"
The value corresponding to Atlanta will be closer to zero than the values registered for Louisville and Denver, so you can arrange them as follows:
D:-2.1 <<<<A: -0.25<0<<<L:1.5
The correct option is C
I hope this helps!
