Question 35725
Given {{{y = (1/3)x +2}}}


a.  Any line parallel to this must have the SAME slope  {{{m= 1/3}}}.  For example, {{{ y = (1/3)x + 5}}}  or {{{ y = (1/3)x -  4}}}


b.  Any line perpendicular to this line must have a slope that is the NEGATIVE RECIPROCAL of this line.  The negative reciprocal of {{{1/3}}} is {{{-3/1}}} or {{{-3}}}.  For example, {{{ y = -3x + 5}}} or {{{ y = -3x -4}}}
