Answer 1

A graphing calculator finds the regression line to be
  y = 5.5x + 52

Answer 2

Answer:

B. $y=5.5x+52$

Step-by-step explanation:

We are given the data set,

x                 y

2               65

4               74

6               81

8               96

10             109

Now, using the regression calculator, we get that,

The linear equation for that matches the data is $y=5.5x+52$.

So, option B is correct.
