<span><span>The average rate of change formula is basically the slope formula, where you plug in: f(b)-f(a)/b-a. Then plug in the numbers. [f(0)=1,f(3)=7)]. So, 7-1/3-0. 6/3 is 2 so the average rate of change is 2. And that makes sense because the average rate of change is always the slope, and the slope is 2.</span></span>

Answer:
$700
Step-by-step explanation:
Given that:
Cost of desktop PC 10 years ago = $6000
Cost of desktop PC 2 years ago = $300
Linear model applies.
To find the rate of decrease per year, we need to find the slope.
One quantity is cost of PC here and second quantity here is number of years.
So, the answer is:
There is a decrease of <em>$700 </em>per year.
OR
Rate of decrease per year is <em>$700</em>.
The correct answer is letter <span> D. Syntax error from line 1 column 53 to line 1 column 60. Unexpected '0'. In order for a number to be considered as irrational when there is no possible ratio for that number. Among the four choices, choice D only tells us that the possible ratio or fraction has a denominator of Zero.</span>
