Write the ordered pair notation of the vector that points from
C(17, -18) to B(17, -32). Find the ||CB|| and its direction.
The staionary vector pointing from the origin to C is $\displaystyle \vec c = \overrightarrow{OC} = (17, -18)$ and similarily $\displaystyle \vec b = (17, -32)$
The vector $\displaystyle \overrightarrow{CB} = \vec b - \vec c = (17, -32)-(17, -18) = (0,-14)$
Obviously it's length is 14 and it has the direction of the negative y-axis.
