Question 1064924
Plot years, t,  on the horizontal axis, and
Income, I,  on the vertical axis
You are given the slope, {{{ 2220 }}} and the
point ( 5, 56000 )
------------------------
Use the point-slope formula
{{{ ( I - 56000 ) / ( t - 5 ) = 2220 }}}
{{{ I - 56000 = 2220*( t - 5 ) }}}
{{{ I - 56000 = 2220t - 11100 }}}
{{{ I = 2220t + 44900 }}}
-----------------------------
check:
Does the line pass through ( 5, 56000 ) ?
{{{ I = 2220t + 44900 }}}
{{{ 56000 = 2220*5 + 44900 }}}
{{{ 56000 = 11100 + 44900 }}}
{{{ 56000 = 56000 }}}
OK
