Charlie used a regression calculator to generate the equation f(x) = –0.15x + 20.1 for the ordered pairs (2, 15), (4, 21), (6, 26), (8, 20), and (10, 14). is a linear representation the best way to represent the data? if it is, explain why. if not, explain why and suggest a better alternative.

The  r -value for the linear function related to the ordered pairs is very close to zero, so it is not a good representation of the data. a quadratic model would better represent the data because there is a turning point within the data set. the data increases then decreases, which is what the graph of a quadratic does. -sample answer

Y’all got to do it all over
