Question

Find the best linear equation for the ordered pairs below.

[(2, 3.5), (4, 4.9), (6, 6.3), (8, 4.6), (10, 2.9)]

y = -.075x +4.89

y = 7x - 12

y = 2x + 6

y = -5.7283x - 1.245

Answer 1

y = -.075x +4.89

Explanation:

The data set has almost no net slope, so the first equation is the most appropriate. (An absolute value function would be a much better fit.)

y = -.075x +4.89
