Answer: A linear relationship
Step-by-step explanation:
From the graph we can see as the number of years increasing the average price of a PC decreasing at a constant rate.
It is forming a straight line and its equation 
is similar to equation of line 
, where m= -39 which is the rate of change of average price.
Hence, the relationship between the average price of PCs and the number of years that have passed since 2000 is a linear relationship.
Answer:
- 8
units
Step-by-step explanation:
<u>We know that:</u>
<u>We can find one side by distance formula:</u>
- a =
- a =
<u>Then the perimeter is:</u>
- P = 4*2 = 8 units
