Question

What is the linear function equation that best fits the data set?

ŷ = x – 2
ŷ = 4x – 11
ŷ = 2x – 2
ŷ = 4x – 2

Answer 1

Option 3

Explanation:

Given data set is,

{(1.5, 1), (2.5, 3), (3, 3), (3, 5), (3.5, 5), (4.5, 7), (5, 7), (5, 9), (5.5, 9), (6.5, 11), (7.5, 13)}

By using linear regression calculator,

Equation of the linear function will be,

y = 2x - 2

Therefore, Option 3 will be the correct option.
