What is the equation of the line of best fit? The points to use are (2,120) and (6,20)

• y = -25x + 170

• y = -5/8x + 170

• y = 25x + 170

• y = 5/8x + 170

What is the line of best fit? The two points you should use are (75,500) and (150,625)

• y = 5/3x + 375

• y = 1/3x + 475

• y = 5/3x + 3

• y = 1/3x + 375
