Someone 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

Option: A is the correct answer.

                    A) y= x+ 10

Step-by-step 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

there is no

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
