To Find: Which linear regression equation best fits the given points?

Solution:

Using regression calculator,

The equation of linear regression that best fits the given points is
`\hat{y}=1.310X+1.9`

So, The linear regression equation best fits the given points (0,2), (0,3), (1,3), (2,3), (4,7), (4,8), (6,10) is
`\hat{y}=1.310X+1.9`
