For which pairs of points can you use a number line to find distance? check all that apply.

(3, –3) and (7, –3)

(1.5, –6) and (–2, 7)

(3, –3) and (–3, 3)

(–2.1, –1) and (–2.1, –5)

(4, 6) and (12, 6)

Correct options are 1,4 and 5.

Step-by-step explanation:

We need to select pairs of points that can use a number line to find distance.

We can use a number to find the distance between two ordered pairs, if x-coordinates of both pairs are same or y-coordinates of both pairs are same.

In option 1, ordered pairs are (3, –3) and (7, –3).

Here, y-coordinates are same. So, a number line can be used to find the distance between (3, –3) and (7, –3).

Distance = 7-3 = 4

In option 2, ordered pairs are (1.5, –6) and (–2, 7).

Here, x and y-coordinates are different.

In option 3, ordered pairs are (3, –3) and (–3, 3).

Here, x and y-coordinates are different.

In option 4, ordered pairs are (–2.1, –1) and (–2.1, –5).

Here, x-coordinates are same. So, a number line can be used to find the distance between (–2.1, –1) and (–2.1, –5).

Distance = -1-(-5) = 4

In option 5, ordered pairs are (4, 6) and (12, 6).

Here, y-coordinates are same. So, a number line can be used to find the distance between (4, 6) and (12, 6).

Distance = 12-4 = 8

Therefore, the correct options are 1, 4 and 5.

good luck!
