Option third "The original amount of the mortgage" is correct because every month that passes, the amount left to pay decreases.
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}[/tex]
[tex]\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
As we know the line of best is represented by:
y = mx + c
Here m is the slope and c is the y-intercept.
A scatter plot is made to model the amount of money left to pay on a mortgage.
Every month that passes, the amount left to pay decreases.
Plug x = 0 to get the y-intercept
y = c
The y-intercept representing the original amount of the mortgage.
Thus, option third "The original amount of the mortgage" is correct because every month that passes, the amount left to pay decreases.
