Question:

For which pair of points can you use this number line to find the distance?

Answer:

Step-by-step explanation:

Given points 1 and 7 on the number line.

Notice that the distance between two points (a,b) and (a,c) can be found by calculating the distance between b and c, the second coordinates; similarly, for a pair of points (x,y) and (z,y), we can find the distance between those two points by calculating the distance between x and z.



Therefore, we need to find pair of point whose form is (a,b) and (a,c) or (a,b) and (c,b).



Notice that that is the case of (-4,1) and (-4, 7), and (-4,-1) and (-4,-7).

For the first pair of points, we need to calculate the distance between 1 and 7, and, as for the second pair of points, the distance between -1 and -7.

Thus, the answer is (-4,1) and (-4,7), the second option top to bottom.
