Question 988946
If what you mean is, what is the equation of the line which passes through those two points A and B, then you can use method like what is shown in this video:


<a href="https://www.youtube.com/watch?v=VDKztVZUgnM">Equation of line through two given points</a>


Once you have in the form  {{{y=(n/d)x+b}}} where slope is {{{n/d}}}, you have what you want  (General Form); but if you really want STANDARD FORM, then simple steps will allow to transformation.


{{{y=(n/d)x+b}}}
{{{y-(n/d)x=b}}}
{{{-(n/d)x+y=b}}}
{{{highlight_green(-nx+dy=bd)}}}
or 
{{{highlight_green(nx-dy=-bd)}}}
or
whatever equivalent method you choose.
