Step-by-step explanation:

Hi there! I'm glad I was able to help you with this problem!

On a number line, the left side decreases in numbers, while the right side increases. Therefore, with the number 7 already given to us on the line, the blue dot is on the third point. All you have to do is count backwards to get your answer. :)

I hope this helped you! Comment below if you have any other questions!
