Question 556990
Use point-slope formula
{{{ ( 14 - y ) / ( 12 - 3 ) = 4/3 }}}
{{{ 3*( 14 - y ) = 4*9 }}}
{{{ 42 - 3y = 36 }}}
{{{ 3y = 42 - 36 }}}
{{{ 3y = 6 }}}
{{{ y = 2 }}} answer
check:
{{{ ( 14 - y ) / ( 12 - 3 ) = 4/3 }}}
{{{ ( 14 - 2 ) / ( 12 - 3 ) = 4/3 }}}
{{{ 12 / 9 = 4/3 }}}
{{{ 12 = 12 }}}
OK
