Answer: (y-5)=\dfrac{-6}{-11}(x-7)

Step-by-step explanation:

We know that the point slope form of a line that passes through two points (a,b) and (c,d) is given by :-

(y-b)=\dfrac{d-b}{c-a}(x-a)

Similar;y , the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1) will be :-

(y-5)=\dfrac{-1-5}{-4-7}(x-7)

(y-5)=\dfrac{-6}{-11}(x-7)

Hence, the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1) is given by :-

(y-5)=\dfrac{-6}{-11}(x-7)

As the equation of the line with two points (a,b) and (c,d) is given by

(x-a)/(c-a) = (y-b)/(d-b)

We have

(x-7)/(-4-7) = (y-5)/(-1-5)

(x-7)/(-11) = (y-5)/(-6)

6(x-7) = 11(y-5)

6x-42=11y -55

11y= 6x-42+55

11y = 6x+13

y=(6/11)x + (13/11) is the respective slope intercept form of it

Answer:

<u>The slope is -3.</u>

Step-by-step explanation:

The slope is the Rise/Run between the two points.  The change in y for every change in x.  Take the two points and calculate the:

RISE = (-6 - 3) = -9

RUN = (8 - 5) = 3

Rise/Run, or slope, is = -9/3 or -3

I graphed a line with slope of -3 and then added 18 to force the line to intersect the two given points.

igor_vitrenko [27]

Answer:


Step-by-step explanation:

Simplified the following system of equations into a linear equation.

Graphed (plot the points) the linear equation onto the graph.

To get the solution (2,-2) (x,y)she went positive 2 to the right and -2 down.

PtichkaEL [24]

By using an excel spreadsheet and IRR function, the cross over rate = 14.85%

Year           Cash Flow (A)           Cash Flow (B)

0                    -58,000                   -58,000

1                      34,000                     21,200

2                     28,000                     25,200

3                     20,000                     30,000

4                      13,600                     25,200

<h3>What is the IRR for each of these projects?</h3>

using an excel spreadsheet and the IRR function:

Project A's IRR = 28.3%

Project B's IRR = 25.7%

(b) If you apply the IRR decision rule, which project should the company accept?

Project A (its IRR is higher)

Requirement 2:

(a) Assume the required return is 14 percent. What is the NPV for each of these projects?

using an excel spreadsheet and the NPV function:

Project A's NPV = $14,921.37

Project B's NPV = $15,156.64

(b) Which project will you choose if you apply the NPV decision rule?

Project B (its NPV is higher)

Requirement 3:

(a) Over what range of discount rates would you choose Project A?

higher than 14.85%

(b) Over what range of discount rates would you choose Project B?

lower than 14.85%

(c) At what discount rate would you be indifferent between these two projects?
