Answer:
The number line is y = 2.
Explanation:
We are given the points (-1,2) , (-5,2) and we have to find the number line that can be used find the distance between them.
The y coordinate of the two points is
same (equal to 2) , so the number line that can be used to find the distance between them is y = 2.
Distance between the points = |-5+1| = 4
