Question 1099202
You are given 2 points on the line:
( 0, 160 )
( 7, 240 )
Note that y-values are in thousands of dollars
--------------------------------------------
Use the general point-slope formula
{{{ ( y - 160 ) / ( x - 0 ) = ( 240 - 160 ) / ( 7 - 0 ) }}}
{{{  y - 160 = ( 80/7 )*x }}}
{{{ y = ( 80/7 )*x + 160 }}}
-------------------------
check:
Does it go through ( 7, 240 )  ?
{{{ y = ( 80/7 )*x + 160 }}}
{{{ 240 = ( 80/7 )*7 + 160 }}}
{{{ 240 = 80 + 160 }}}
{{{ 240 = 240 }}}
OK
