where m is the slope and b is the y-intercept.
Also,
Let us choose the coordinates and
Substituting, we get,
Thus, the formula becomes
Now, to determine the value of b, let us substitute in the formula,
we get,
Substituting the value of b in the formula, we have,
Thus, the y-intercept is
At y-intercept the value of x is 0. It means the y-intercept represents the amount of money left to pay on a credit card when the number of months is 0.
Thus, the y-intercept represents the original balance on the credit card.
Hence, Option d is the correct answer.
