I need help graphings this in Excel, I am not getting the right best fit line equation.
It needs to be cell voltage (Ecell) as a function of Log[Cu+2]
| Ecell | Log(Cu+2) |
| 1.034 | 0 |
| 1.204 | -2 |
| 1.017 | -3 |
| 1.1 | -4 |
| 1.011 | -5 |
| 0.992 | x |

First, plot the given points in Excel. Then right click on any one of the points and select the add trendline option. Automatically a linear trendline would be added.
Identify the encircled points (in black) in the graph, to find the equation of the line y = mx + C
The encircled points (x,y) are (-5, 1.06) and (0,1.09)
Solving for m and C,
For (0, 1.09) , 1.09 = m(0) + C => C = 1.09
For (-5, 1.06), 1.06 = m(-5) + 1.09 => m = 0.006
Thus, the equation of the line is y = 0.006x + 1.09
Solve, this equation for y = 0.992
0.992 = 0.006(x) + 1.09 => x = -16.34

Please use excel, need help with functions because I am only used to using a financial calculator, thanks! The following cash-flows have two IRRs. Draw a graph of the NPV of these cash flows as a function of the discount rate. Then use the IRR function to identify the two IRRs. Would you invest in this project if the opportunity cost were 20%?
