Question 905664
{{{ T = f( N ) }}}
Plot Temp on the vertical axis
Plot Number of chirps on horizontal axis
The given points are:
( 113, 73 )
( 172, 87 )
Use the general point-slope formula
{{{ ( T - 73 ) / ( N - 113 ) = ( 87 - 73 ) / ( 172 - 113 ) }}}
{{{ ( T - 73 ) / ( N - 113 ) = 14 / 59 }}}
{{{ 59*( T - 73 ) = 14*( N - 113 ) }}}
{{{ 59T - 4307 = 14N - 1582 }}}
{{{ 59T = 14N + 2725 }}}
{{{ T = (14/59)*N + 46.186 }}}
---------------------------
check answer:
( 113, 73 )
{{{ T = (14/59)*N + 46.186 }}}
{{{ 73 = (14/59)*113 + 46.186 }}}
{{{ 73 = 26.814 + 46.186 }}}
{{{ 73 = 73 }}}
OK
