When discount points are paid, the bank collects a one-time fee at closing in exchange a lower mortgage rate to be honored for the life of the loan.
The banks consider this payment to be "prepaid mortgage interest". Meanwhile, mortgage interest is tax-deductible for eligible tax-filers so, for many mortgage borrowers, there's a tax advantage to paying discount points.
Option B:
The linear equation that best describes the model is y = 40x + 800.
Solution:
Take two points which exactly on the line.
Let the points are (0, 800) and (10, 1200).

Slope of the line:



m = 40
y-intercept of the line is where the line crosses at y-axis.
y-intercept (b) = 800
Equation of a line:
y = mx + b
y = 40x + 800
The linear equation that best describes the model is y = 40x + 800.
Option B is the correct answer.
Answer:
defined as the average value of the function over its domain
Hello!
For this one, all of them look like you can use mental math, but maybe choose the two middle ones and the bottom right one.
Hope this helps :))
