Question 1006054
More than one way to do it.


{{{y=mx+b}}}
{{{b=y-mx}}}


{{{-9y=-2x-12}}}
{{{y=(2/9)x+4/3}}}


Look for equation  {{{y=-(9/2)x+b}}} and form b using the couple of steps-result shown near the top of the page field.


{{{y=-(9/2)x+(3-(-9/2)(-2))}}}
and this just needs to be simplified.
