Exercises: Interpret the Slope and Intercept of a Linear Model
Work through each section in order. For every interpretation, write a full sentence about the real situation and include UNITS. Remember: the slope is a rate of change (y-units per x-unit) and the intercept is the predicted value when x = 0 (in y-units) — but the intercept is only meaningful when x = 0 is realistic and near the data.
