The data in Table 5 represent the club-head speed and the distance a golf ball travels for eight swings of the club. We found that these data are linearly related .

(a) Find a linear equation that relates club-head speed, x (the explanatory variable), and distance, y (the response variable), by selecting two points and finding the equation of the line containing the points.

(b) Graph the line on the scatter diagram.

(c) Use the equation to predict the distance a golf ball will travel if the club-head speed is 104 miles per hour.

Approach

(a) Perform the following steps:
