Question 984578
Use the idea shown here, although used slope-intercept equation and different example:
<a href="https://www.youtube.com/watch?v=VDKztVZUgnM">Linear Equation through Two Given Points</a>


Once done, use this idea:
If this is your slope-intercept form equation: {{{y=(n/d)x+b}}}
Take these steps:
{{{d*y=d((n/d)x+b)}}}, using {{{n/d}}} as the slope
{{{d*y=nx+bd}}}
{{{d*y-nx=b*d}}}
{{{highlight_green(nx-dy=-bd)}}}------standard form symbolically derived from slope-intercept form.
