+
+## Description
+REGR_INTERCEPT is used to calculate the y-intercept of the least squares-fit
linear equation for a set of number pairs.
+
+## Syntax
+```
+REGR_INTERCEPT(y, x)
+```
+
+## Parameters
+- `y` (Numeric): The dependent variable.
+- `x` (Numeric): The independent variable.
+
+Both `x` and `y` support basic numeric types.
+
+## Returned values
+Returned data type: FLOAT64
+
+The function returns the y-intercept of the linear regression line.
+
+If there are no rows, or only rows with null values, the function returns NULL.
+
+## Examples
+```sql
+-- Example 1: Basic Usage
+SELECT regr_intercept(y, x) FROM test;
+
+-- Example 2: Usage in a query with sample data
+SELECT * FROM test;
++------+------+------+
+| id | x | y |
++------+------+------+
+| 1 | 18 | 13 |
+| 3 | 12 | 2 |
+| 5 | 10 | 20 |
+| 2 | 14 | 27 |
+| 4 | 5 | 6 |
++------+------+------+
+
+SELECT regr_intercept(y, x) FROM test;
++----------------------+
+| regr_intercept(y, x) |
++----------------------+
+| 5.512931034482759 |
++----------------------+
+```
+
+## Usage notes
+- This function ignores any pair where either value is null.
+- In cases where the calculation would result in a division by zero, the
function will return NULL.
+
+## Related functions
+REGR_SLOPE, REGR_R2, REGR_COUNT, REGR_AVGX, REGR_AVGY
+
+## References
+For more details about linear regression functions, please refer to the SQL
standard documentation on aggregate functions.
