## What is the slope of a trendline in Excel?

Examine the equation for the line, which Excel is now displaying overlaid on the scatter plot. The equation will be in the form of “y = mx + b” where m and b will be numbers. The value of “m” is the slope of the graph. For example, if the equation is y = 5.2x + 7, the slope is 5.2.

## What is the equation for line of best fit?

Step 1: Calculate the mean of the x -values and the mean of the y -values. Step 4: Use the slope m and the y -intercept b to form the equation of the line. Example: Use the least square method to determine the equation of line of best fit for the data.

## How do you interpret slope equations?

If the slope is given by an integer or decimal value we can always put it over the number 1. In this case, the line rises by the slope when it runs 1. “Runs 1” means that the x value increases by 1 unit. Therefore the slope represents how much the y value changes when the x value changes by 1 unit.
