Question 30654
(8,-5)
-5x-4y=3 
Solve for y
{{{ -5x-4y=3 }}}
{{{ -4y=5x+3 }}}
{{{ y= -5x/4-3/4 }}}
Parallel means same slope.  plug in slope and points and solve for b.
{{{ y=mx+b }}}  
{{{ -5=(-5/4)(8)+b }}} 
{{{ -5 = -10 + b }}} 
{{{ 5 = b }}}
Plug slope and b back into y=mx+b
{{{ y=mx+b }}}
{{{ y=(-5/4)x +5 }}}

{{{ graph( 300, 300, -10, 10, -10, 10, -5x/4-3/4, (-5/4)x +5 ) }}}
