a) State the initial value and what it represents in this situation.

b) State the rate of change and what it represents in this situation.

c) State the type of relation.

d) Describe the rate of change (constant or not constant). Explain your
answer.

e) State whether the relation is an example of partial or direct variation.
Explain your answer.

a) the initial value is $125, and it represents the cost Navin has to pay in the beginning

b) the rate of change is  $20 per month, and it represents the cost he has to pay per month

c) linear; the equation for it is y = 20x + 125

d) The rate of change is constant because each month, Navin always has to pay $20.

e) This is partial variation because the equation y = 20x + 125 doesn't follow y = kx
