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 Mark this and return
