Question

Which points are separated by a distance of 3 units?A. (1,5) (1,3)B. (3,6) (3,8)C. (4,2) (4,7)D. (2,7) (2, 4)

Answer 1

Let us consider the points (2,7) and (2,4)

Here since the x cordinate is same so they lie in the line x=2.

Now their distance will be

$\begin{gathered} d=7-4 \\ d=3 \end{gathered}$

Hence option D is correct.
