Question

Someone please helppp.....

Which function BEST expresses the linear relationship displayed by the scatter plot?

A) y= x+ 10
B) y= x+ 19
C) y= 10x + 19
D) y= 19x + 10

Answer 1

I believe that the answer would be B) y = x + 19

Answer 2

Option: A is the correct answer.

A) y= x+ 10

Explanation:

We are given a set of data values on the scatter plot as follows:

x y

9 19

9 20

11 21

12 21

13 23

14.5 24

15 25

16 25

Now the line of best fit that best represents these data points are:

y=x+10

Also, the r-value of this line of best fit is close to 1.

Hence, the function that best expresses the linear relationship displayed by the scatter plot is:

y=x+10
