The table shows the number of free throws a player makes in a basketball game and the number of points the player scores in the
game. Number of Free Throws vs. Number of Points Scored Number of Free Throws Made (f) Number of Points Scored (s) 5 15 3 11 8 20 7 18 9 21 Alex used a regression calculator to find the equation of the trend line y = a x + b for the data in the table. He rounded the values for a and b on his calculator as shown below. a = 1.7. b = 6.2 Which trend line compares the data in the table? s = 1.7 f + 6.2 s = 6.2 f + 1.7 f = 1.7 s + 6.2 f = 6.2 s + 1.7
Given data in that table forms the 2x3 matrix shown below 2 7 6 5 4 5 a 3-point field goal is worth 3 points a normal field goal is worth 2 points a free throw is worth 1 points.
this is because the amount of points he scores is equal to 1.7 times the free-throws he makes + 6.2, so our equation in slope intercept form is s = 1.7f + 6.2
