The blue dot is at what value on the number line?<br> PLEASE HELP FAST
Elodia [21]

Answer:

-22

Step-by-step explanation:

The blue dot on the number line is 4 units below -10. The number -16 is also labeled, but it is instead just 2 units below -10. If -16 is 2 units below -10, then 2 units is equal to a distance of 6, which means 1 unit is equal to a distance of 3. Because the blue dot is 4 units below -10, the blue dot is 12 less than -10, meaning that the blue dot is at -22.
