Write an equation in slope intercept form (4,-2) (0,-5)​
Zarrin [17]

Answer:

y=-7/4x+5

Step-by-step explanation:

The line contains points at (4,-2) and (0,-5)

(y1-y2) / (x1-x2) = slope

(4,-2) =(x1,y1)

(0,-5) = (x2,y2)

(-2-5) / (4-0)

-7 / 4 = -7/4

y= -7/4x + b

plug in points for x and y to find b

-2=-7/4(4)+b

-2=-7+b

5=b

y=-7/4x+5

Suppose an initial investment of $100 will return $50/year for 3 years (assume the $50 is received each year at the end of the y
nydimaria [60]

With a positive NPV, it shows that the investment is profitable.

It is a profitable investment with a positive NPV at a discount rate of 20%.

Data and Calculations

Initial investment = $100

Annual cash inflows = $50

Period of investment = 3 years

Discount rate = 20%

<h3>What is the present value?</h3>

Present value (PV) is the current value of a future sum of money or stream of cash flows given a specified rate of return.

Present Value (PV) annuity factor for 3 years at 20% = 2.106

Present value of annual cash inflows = $105.3 ($50 x 2.106)

Net Present Value (NPV) = $5.3 ($105.3 - $100)

Thus, with a positive NPV, it shows that the investment is profitable.
