Which of the following equations could be the equation for the line of best fit for the given set of data?
x y
3 –0.25
5 –1.00
7 –1.50
9 –1.75
11 –2.25
13 –2.25
15 –2.75
17 –3.25
19 –3.
21 –3.50

a)y = 2/11x + 1/11
b)y = -2/11x + 11
c)y =2/11x -11
d)y= -2/11x -11

Answer with Step-by-step explanation:

x     y

3   0.25

5  1.00

7  1.50

9  1.75

11  2.25

13  2.25

15  2.75

17  3.25

19  3.

21  3.50

As we can see the value of y when x=5 is 1

Which is satisfied by equation in part A) only

Hence, the correct option is:

A)y = 2/11x + 1/11

can you me with homework?

step-by-step explanation:

the answer to the question is a  

it has the same slope and the same y-intercept.
