Data were collected on the distance a golf ball will travel when hit by a golf club at a certain speed. The speed, s, is measured in miles per hour, and distance, y, is measured in yards. The regression line is given by = 5.32 + 46.73s.

Identify the slope and y-intercept of the regression line. Interpret each value in context.

a. The slope, b = 5.32, indicates that the distance increases by 5.32 yards for every one mile per hour of speed. The y-intercept, a = 46.73, is the distance estimated by this model if the speed is zero miles per hour.

b. The slope, b = 5.32, indicates that the distance decreases by 5.32 yards for every one mile per hour of speed. The y-intercept, a = 46.73, is the distance estimated by this model if the speed is one mile per hour.

c. The slope, b = 46.73, indicates that the distance increases by 46.73 yards for every one mile per hour of speed. The y-intercept, a = 5.32, is the distance estimated by this model if the speed is zero miles per hour.

d. The slope, b = 46.73, indicates that the distance decreases by 46.73 yards for every one mile per hour of speed. The y-intercept, a = 4.17, is the distance estimated by this model if the speed is one mile per hour.

e. The slope and y-intercept are unable to be determined from the regression line given.
