Which number line can be used to find the distance between (4, -1) and (8, -1)?

Answer:
I am not sure, but I believe it is the last one. Sorry if it's not right.
Answer:
The first number line
Step-by-step explanation:
Hey There!
The answer is the first number line because the y values in the given coordinates are the same so all we have to do is plot the x values (4 and 8) and we can find the distance between the two points. The first number line has 4 and 8 on it therefore that is the answer.
