Question 1108279
Youare given 2 points on a straight line
( 2, 42000 )
( 6, 30000 )
Plot time, {{{ t }}}, on the horizontal axis
Plot value, {{{ V }}}, on the vertical axis
-------------------------------------
The slope is:
[ change in {{{ V }}} ] / [ change in {{{ t }}} ]
{{{ m = ( 30000 - 42000 ) / ( 6 - 2 ) }}}
{{{ m = -12000 / 4 }}}
{{{ m = -3000 }}} dollars/yr
---------------------------
The slope tells you how fast the value is decreasing
It decreases $3,000 each year
