Give the slope and y-intercept for each of the lines graphed Question

Question 1 10.6 a.y = 4 + x y = 5 – 2x y = –4 + 3x y = –2x y = x y = .50 + 1.5x Give the slope and y-intercept for each of the lines graphed Question 2 10.19 Ranking driving performance of professional golfers. Refer to The Sport Journal(Winter 2007) study of a new method for ranking the total driving performance of golfers on the Professional Golf Association (PGA) tour,  javascript:findAnchor('ch02qa20q3')Exercise 2.50 (p.  javascript:findAnchor('ch02qa20q3')63). Recall that the method computes a driving performance index based on a golfer’s average driving distance (yards) and driving accuracy (percent of drives that land in the fairway). Data for the top 40 PGA golfers (as ranked by the new method) are saved in the PGADRIVER file. (The first five and last five observations are listed in the table.) Rank Player Driving Distance (yards) Driving Accuracy (%) Driving Performance Index 1 Woods 316.1 54.6 3.58 2 Perry 304.7 63.4 3.48 3 Gutschewski 310.5 57.9 3.27 4 Wetterich 311.7 56.6 3.18 5 Hearn 295.2 68.5 2.82 ? ? ? ? ? 36 Senden 291 66 1.31 37 Mickelson 300 58.7 1.30 38 Watney 298.9 59.4 1.26 39 Trahan 295.8 61.8 1.23 40 Pappas 309.4 50.6 1.17 Source: Wiseman, F., et al. “A new method for ranking total driving performance on the PGA Tour,” The Sport Journal, Vol. 10, No. 1, Winter 2007 (Table 2). Write the equation of a straight-line model relating driving accuracy (y) to driving distance (x). Fit the model, part a, to the data using simple linear regression. Give the least squares prediction equation. Interpret the estimated y-intercept of the line. Interpret the estimated slope of the line. In  javascript:findAnchor('ch02qa53q1')Exercise 2.126 (p.  javascript:findAnchor('ch02qa53q1')95), you were informed that a professional golfer, practicing a new swing to increase his average driving distance, is concerned that his driving accuracy will be lower.
