Determine whether the following graph is a direct variation. Explain how you came to your conclusion.

It is not a direct variation becuase though it goes through the orgin, its curved rather than straight.

Principal

Step-by-step explanation:

Since, the amount in the simple interest is,

Where, P is the principal amount,

r is the annual rate,

t is the time ( in years ),

Here, r = 3.75 %, t = 6 years,

Thus, By the above explanation,

It is clear that, we need the value of P, that is, principal to find the amount.
