Answer 1

x - The predictor variable.

y - The response variable.

R squared - The proportion of variation in the response variable that is explained by the model.

slope -  The predicted change in the response variable for a 1 unit change in that predictor variable, holding all other variables constant.

residual -The distance between an observed value and it's predicted value on the line of best fit.

b0 , β0 - The population value of the response variable when all predictor variables are zero.
