Question 724621
Slope = ( change in y ) / ( change in x )
{{{ ( 3 - 2/3 ) / ( x - 1/2 ) = 2 }}}
{{{ 9/3 - 2/3 = 2*( x - 1/2 ) }}}
{{{ 7/3 = 2x - 1 }}}
{{{ 2x = 10/3 }}}
{{{ x = 5/3 }}}
check answer:
{{{ ( 3 - 2/3 ) / ( 5/3 - 1/2 ) = 2 }}}
{{{ ( 9/3 - 2/3 ) / ( 10/6 - 3/6 ) = 2 }}}
{{{ (  7/3 ) / ( 7/6 ) = 2 }}}
{{{ ( 1/3 ) / ( 1/6 ) = 2 }}}
{{{ 1/3 = 2*(1/6) }}}
{{{ 1/3 = 1/3 }}}
OK
