Question 1147207
( 12, -4 )
( 6, -2 )
--------------
Use the general point slope formula
{{{ ( y -(-4) ) / ( x - 12 ) = ( -2 -(-4) ) / ( 6 - 12 ) }}}
{{{ ( y + 4 ) / ( x - 12 ) = 2 / (-6)  }}}
{{{ ( y + 4 ) / ( x - 12 ) = -1/3 }}}
{{{ 3*( y + 4 ) = -1*( x - 12 ) }}}
{{{ 3y + 12 = -x + 12 }}}
{{{ 3y = -x }}}
{{{ y = ( -1/3)*x }}}
--------------------------
check answer:
( 12, -4 )
{{{ -4 = (-1/3)*12 }}}
{{{ -4 = -4 }}}
OK
------------
( 6, -2 )
{{{ -2 = (-1/3)*6 }}}
{{{ -2 = -2 }}}
OK
