Question 648496


{{{slope}}} is {{{rise}}} over {{{run}}}, meaning the differences of {{{y}}} over the differences of {{{x}}}
 
If you have ({{{1}}},{{{k}}}) and ({{{5}}}, |{{{ k}}}|), then the difference of the {{{y-coordinates}}} is  

 (|{{{k}}}|-{{{k}}})/({{{5-1}}})...so it could be   {{{(k-k)/(5-1)=0}}}, or

{{{ (-k-k)=-2k/4=-k/2}}}, and 

the difference of the {{{x-coordinates}}} is {{{5-1=4}}}
 
so,  {{{m=-k/2}}}

if {{{m=3}}}, then {{{3=-k/2}}}....->...{{{3*2=-k}}}->...{{{6=-k}}}..->...{{{-6=k}}}
and, your points will be

({{{1}}},{{{-6}}}),({{{5}}}, {{{6}}}); {{{m=3}}}
