Answer with explanation:
The Meaning of partial Representation is that ,you can't completely describe the situation with the Information Provided.
The given linear equation in two variable is
y = x+4
Where , y is total monthly charge of a cell phone bill.
x=Amount charged per minute for cell phone bill.
$ 4=Monthly fee in addition to the data and minutes charges on her cell phone bill
→→The two representations which are considered to be only partial representations are:
Option C: The table and the equation
Option D: The graph and the table
Because with the help of above two you can't describe what you are talking about, because a linear equation in two variable can represent any other situation also, like difference between me and my sister's age is 4 years.It can be any other verbal representation also.So,to describe this situation verbal representation of this information is also Salient.
