The correct option is 2.

Step-by-step explanation:

The given data is

x               y

5              36

9              64

12            72

18            96

26           141

35           189

The general form of regression line is

y\approx ax+b

From the given picture of graphing calculator, it is clear that the equation of regression line is

y\approx 5.098x+9.118

Approx the value of a and b upto tenth.

y\approx 5.10x+9.12

The equation of the line of best fit is y ≈ 5.10x+9.12. Therefore the correct option is 2.
