Find the distance between two points given their coordinates.
-Find the distance between points $R$ and $S$ on a number line, with coordinates 8 and $- 7$, respectively.
A) $d ( R , S ) = 1$
B) $d ( R , S ) = - 1$
C) $d ( R , S ) = - 15$
D) $\mathrm { d } ( \mathrm { R } , \mathrm { S } ) = 15$

Question

Quizplus · Accepted Answer

The distance between two points on a number line is the absolute value of the difference between their coordinates. Thus, $d(R, S) = |8 - (-7)| = |8 + 7| = 15$.
