Question 1136391
use point-slope formula
{{{ ( y - 24.9 ) / ( x - 35 ) = ( 42.4 - 24.9 ) / ( 0 - 35 ) }}}
{{{ ( y - 24.9 ) / ( x - 35 ) = 17.5 / (-35 ) }}}
{{{ ( y - 24.9 ) / ( x - 35 ) = -1/2 }}}
{{{ 2*( y - 24.9 ) = -1*( x - 35 ) }}}
{{{ 2y - 49.8 = -x + 35 }}}
{{{ 2y = -x + 84.8 }}}
{{{ y = -.5x + 42.4 }}}
----------------------------
check answer:
( 0, 42.4 )
{{{ y = -.5*0 + 42.4 }}}
{{{ y = 42.4 }}}
OK
----------
( 35, 24.9 )
{{{ y = -.5*35 + 42.4 }}}
{{{ y = -17.5 + 42.4 }}}
{{{ y = 24.9 }}}
OK
