Definitions:

Slope

In the context of a regression line, the slope represents the rate at which the dependent variable changes with respect to the independent variable, indicating the strength and direction of the linear relationship.

Intercept

The point at which a line or curve crosses an axis in a graph, often representing the starting or baseline value of the dependent variable when all other variables are held at zero.

Simple Linear Regression

A statistical method to model the relationship between a single independent variable and a dependent variable by fitting a linear equation to observed data.

SSE

Sum of Squares due to Error, a measure used in statistical analysis to quantify the variance within data points from the observed values.
