Find the slope of the line that passes through the pair of points listed below.<br> (-2, -3), (6,5)
antoniya [11.8K]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =5\\y_{1} =-3\\x_{2} =6\\x_{1} =-2

^^^Plug these numbers into the formula for slope...

\frac{5-(-3)}{6 - (-2)}

\frac{8}{8}

1

^^^This is your slope

Hope this helped!

Problem 10-01 NPV A project has an initial cost of $66,950, expected net cash inflows of $14,000 per year for 9 years, and a cos
svlad2 [7]

Answer:

NPV = $13,676.33

Step-by-step explanation:

First, find the present value of the cash inflows. You can solve this question using a Financial calculator;

14,000 per year is a recurring cashflow hence the PMT

PMT = 14,000

I/Y = 10%

N= 9

FV =0

then CPT PV = 80,626.33

NPV = -Initial investment + PV of future cash inflows

NPV = -66,950 + 80,626.33

NPV = $13,676.33

"NPV" button, then , then "CPT".

The answer to the NPV = $13,676.33
