Find the distance between two points given their coordinates.
-Find the distance between points $\mathrm { P }$ and $\mathrm { Q }$ on a number line, with coordinates $- 7$ and 4 , respectively.
A) $d ( P , Q ) = - 11$
B) $\mathrm { d } ( P , Q ) = - 3$
C) $d ( P , Q ) = 11$
D) $d ( P , Q ) = 3$

Question

Quizplus · Accepted Answer

The distance between two points on a number line is the absolute value of the difference between their coordinates. Thus, $d(P, Q) = |4 - (-7)| = |4 + 7| = 11$.
