# SLOPE

Returns the slope of the linear regression line through data points in known_y's and known_x's. The slope is the vertical distance divided by the horizontal distance between any two points on the line, which is the rate of change along the regression line.

**Syntax**

**SLOPE**(**known_y's**,**known_x's**)

**Known_y's** is an array or cell range of numeric dependent data points.

**Known_x's** is the set of independent data points.

**Remarks**

- The arguments must be either numbers or names, arrays, or references that contain numbers.
- If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
- If known_y's and known_x's are empty or have a different number of data points, SLOPE returns the #N/A error value.
- The equation for the slope of the regression line is:

**Example**

`SLOPE({2,3,9,1,8,7,5},{6,5,11,7,5,4,4})`

equals 0.305556
