Question

Which linear regression equation best fits the given points?

Answer 1

We are going to choose a line:
 y = -7 / 5x + 7.6
 To verify that it is the line that best suits, we evaluate some points.
 For (0, 8):
 y = -7 / 5 (0) +7.6
 y = 7.6
 For (6, 0)
 y = -7 / 5 * (6) +7.6
 y = -0.8
 For (1, 6)
 y = -7 / 5 * (1) +7.6
 y = 6.2
 We observe that the results are very similar to the coordinate y of each point evaluated.
 Therefore, the equation is a good approximation.
 Answer:
 A linear regression equation that best fits the given points is:
 y = -7 / 5x + 7.6
