1. Denotes the variable plotted on the horizontal axis and called the explanatory variable.
2. Denotes the variable plotted on the vertical axis and is called the response variable.
3. The regression coefficient = the change in Y for a change in X of +1.
4. The amount of variability of Y explained by X.
5. The strength of the linear relationship between X and Y.
