Mathematics: What is the equation of the line of best fit given by a regression calculator for the data in the table? x 5 9 12 18 26 35 y 36 54 72 98 141 189 A calculator screen. A 2-column table with 6 rows titled Data. Column 1 is labeled x with entries 5, 9, 12, 18, 26, 35. Column 2 is labeled y with entries 36, 54, 72, 98, 141, 189. The regression equation is y almost-equals 5.098 x + 9.118; r almost-equals 0.999. y almost-equals 5.10 x minus 9.12 y almost-equals 5.10 x + 9.12 y almost-equals 9.12 x minus

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.
