Question 1003575
I will say that the house was puchased in year {{{ 0 }}}
The end of the 1st year is year {{{ 1 }}}
------------------
{{{ V(t) = m*t + b }}}
{{{ V(t) }}} is plotted on the vertical axis
{{{ t }}} is plotted on the horizontal axis
{{{ b }}} is value of {{{ V(0) }}}
--------------------------
{{{ m = ( 92000 - 78000 ) / 7 }}}
{{{ m = 14000/7 }}}
{{{ m = 2000 }}}
---------------
{{{ V(0) = 2000*0 + b }}}
{{{ 78000 = 0 + b }}}
{{{ b = 78000 }}}
----------------
The equation is:
{{{ V(t) = 2000t + 78000 }}}
