Use a formula to find the monthly payment on a home mortgage of $84,400 at 4.884% interest for 15 years.
leonid [27]
The applicable formula is
  A = P(r/12)/(1 -(1+r/12)^(-12n))
where P is the principal amount,
r is the annual interest rate (compounded monthly), and
n is the number of years.

Using the formula, we find
  A = 84,400*(0.04884/12)/(1 -(1+0.04884/12)^(-12*15))
  = 84,400*0.00407/(1 -1.00407^-180)
  = 343.508/0.518627
  ≈ 662.34

The monthly payment on a mortgage of $84,400 for 15 years at 4.884% will be
  $662.34

.......... is the slope zero
Eddi Din [679]

Answer:


Step-by-step explanation:

OK... You have to use this formula: <u>Y2 - Y1</u>

                                                          X2 - X1

  • -2 represents X1
  • 7 represents Y1
  • 2 represents X2
  • -5 represents Y2    

<u>Y2 - Y1</u>

X2 - X1

<u>-5 - 7</u>

2 - - 2

<u>-12</u>

-2

Simplify by dividing both -12 & -2 by 2: <u>-6</u>

                                                                 -1

It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...

                -1
