Excel has a built-in function that helps you find the slope of a logarithmic graph. What caught my eye is that Excel lets you find the slope of any type of graph, not just logarithmic ones.

This article will show you how to find the slope of a logarithmic graph in Excel, and what it means for you. Let’s get started!

**How To Find The Slope of The Logarithmic Graph In Excel**

Logarithmic graphs have an inverse function to linear graphs. This means that when the values on a logarithmic graph increase by one unit, the values become exponentially larger. When the values on a linear graph increase by one unit, they stay constant. Because the values on the logarithmic graph increase exponentially, when they increase by one unit they will take a long, long time to reach the next unit. In other words, a logarithmic graph’s slope is negative.

**Here is an example of a logarithmic graph:**

Find The Slope of The Logarithmic Graph In Excel To find the slope of a logarithmic graph we draw two straight lines and find their intersection point. We then plot their inverse functions. This way we can find the slope of the graph. If you don’t have Excel, it’s still possible to find the slope of a logarithmic graph in algebra. Simply complete this set of problems:

**1. Find a negative number when given one.**

**2. The function f(n) = [2^-n] + 1 is defined for real numbers (that is, numbers with digits to the right of the decimal point). Find a positive number when given one.**

**3. f(n) = n^2 – 2n is defined for the negative integers. Find a positive number when given one. 4. The function g(n) = (2^4 – n)^2 is defined for the positive integers.**

**Here are the steps to find the slope of a logarithmic graph in Excel:**

Draw two straight lines and then plot their inverse functions on Excel’s Graphs menu. You will have to change the graph settings to see your straight lines. Logarithmic graph distance between two points.

**Click Graph > Calculate > Inverse** function and select the line you drew with your equation (mine is x = 1.68) from the “From:” pull-down. The slope of our graph is now known.

If you’re using Microsoft Excel 2007 or higher, there are a couple of ways you can improve these results:

1. You can change how round things are.

**Click on Tools > Options > Calculation**, then remove the checkmark from** “Round results to multiple of”** and put in a number like 0.5 or 1.0. For example, if you input 0.5, it will display all numbers up to .5 as .5 and all numbers higher than .5 as the next whole number, for example, 2 would be displayed as 3.

2. You can have the Inverse Function appear above your lines rather than below them. This will allow you to easily measure the distance between two points.

**Click on Tools > Options > Calculation**, then remove the checkmark from **“Put results of functions above cells containing the function.”**

## Logarithmic Scale: Graphing in Microsoft Excel

**How To Make A Logarithmic Scale In Excel**

What you need:

**a) your logarithmic graph**

**b) a ruler/tempera.**

Steps:

1) Print out the graph. Make sure that the print options are set to borderless, fit page to paper, print background colors as is, and no scaling or reducing of any kind. I usually make sure that everything is set so that it prints like a normal sheet of paper (not scaled down). This will allow you to move the scale without losing accuracy.

2) Tape down your ruler/tempera to your graph. Make sure that as far as you can see there are no gaps between the graph and the ruler/tempera. In the parts where there will be no lines on the scale, it’s okay if there is a gap or if it doesn’t look perfect because your eye will form a line in between those spots.

3) Move the ruler so that you get an entire scale of numbers. On a laptop or monitor with a small, tall screen, this might be easier. Sometimes it’s easier to move the ruler when you can see the whole graph. If you are unable to get an entire scale, just make sure that you have as much as possible.

4) Take off your ruler/tempera and save your graph so that you do not lose accuracy. You now have a logarithmic scale.

**How To Find Slope on Excel Graph MAC**

The steps are similar to finding slope on Excel graph windows except you have to do a lot more work because there’s no function in the Excel MAC version to help you.

**Here are the steps:**

If you’re on a MAC, you can find the slope of a logarithmic graph in Excel by using the formula below:

=SLOPE(2,1.68)

The other way you can find the slope on MAC is as follows:

**1. Select BOTH the x and y axis by holding ctrl key + clicking on the mouse.**

**2. Change them to a %**

**3. Now you should be able to see a slope**

**Conclusion**

We hope we have enlightened you about finding the slope of the Logarithmic Graph in Excel. Thanks for staying with us.

Meta Description: The slope of the logarithmic graph is an easy calculation to make if you have Excel. Use the slope finder function in Excel to find the difference in values between x-values and y-values.
