Answer:

y = 20   x = 6

Step-by-step explanation:

1 (3x+ 2y = 58 ------------>  -3x + -2y = -58

1x + 2y = 46 -------------->    1x + 2y = 46  

                                              ____________

                                                -2x  =  -12

                                               -----------------

                                                -2x       -2x

                                                 x = 6

3(6) + 2y = 58

18 + 2y = 58

-18          -18                                    

------------------

       2y = 40

      -----  -----

       2y     2y

y = 20

The line of the best fit is y = 4.71x—30.31 and at x = 9.5 inches the value of y is 14.5 oz.

<h3>What is the line of best fit?</h3>

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

First, we need to find the line of best fit:

Let's suppose the line of the best fit is:

y = mx + c

We can find the value of m:

\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}   and

\rm c = \dfrac{\sum y -m \sum x}{n}

After calculating, we will get:

m = 4.71

d = -30.31

y = 4.71x—30.31

Plug x = 9.5

y = 14.43 ≈ 14.5 oz

Thus, the line of the best fit is y = 4.71x—30.31 and at x = 9.5 inches the value of y is 14.5 oz.
