<PRE><B>Question 1146617</B>
&lt;br&gt;
One simple form of a linear equation specifies the starting value and the rate of change (slope):&lt;br&gt;
{{{y = mx+b}}}&lt;br&gt;
The slope is m, the starting value is b.&lt;br&gt;
The starting value is 20000.&lt;br&gt;
The change in value is from 20000 to 2600 in 10 years.  That&#39;s a change of -17400 in 10 years, a rate of -17400/10 = -1740 per year.  So&lt;br&gt;
{{{y = 20000-1740x}}}&lt;br&gt;
where y is the value and x is the time in years since the purchase.&lt;br&gt;
Your post says &quot;select&quot; a linear equation, but you don&#39;t show the choices.&lt;br&gt;
Find one which is equivalent to the one shown.</PRE>
