Regression Equation: The regression equation is a mathematical model that describes the linear relationship between a dependent variable (y) and one or more independent variables (x). It is used to predict the value of the dependent variable based on the values of the independent variable(s).
Slope: The slope is a measure of the steepness of a line in a coordinate plane. In the context of a regression equation, the slope represents the rate of change in the dependent variable (y) for a one-unit change in the independent variable (x).
Coefficient of Determination (R-squared): The coefficient of determination, also known as R-squared, is a statistical measure that represents the proportion of the variance in the dependent variable (y) that is predictable from the independent variable(x). It is a measure of the goodness of fit of the regression model.
