To find our solution, we first write the equation in the following form:
In this formula a represents the slope, therefore:
Because the line passes through the point P(5, -7), we can fill in the coordinates of this point in the formula and we get the following:
Now, add up 1 to both sides and we get
So the formula will be:
Bringing x to the other sides gives us:
Finally we multiply by 5 to get our standard form (and therefore our final answer):
Hence, the answer is D.

Invested amount (P) = $300.
Time in years (t) = 2 years.
Balance after 2 years (A) = $329.49.
Let us assume rate of interest = r % compounds annually.
We know, formula for compound interest
Plugging values in formula, we get
Taking square root on both sides, we get
r=0.048.
Converting it into percentage by multiplying by 100.
r=0.048 × 100
r = 4.8 %
Therefore, the rate of interest on the account is 4.8% compounds annually.
