irakobra [83]

Answer:

A. y=-8.583x+475.215

Step-by-step explanation:

We are given,

The table representing the closing prices of stock for the last five days is,

Day                         Value

1                                472.08

2                               454.26

3                                444.95

4                                439.49

5                                436.55

Using the linear regression calculator, we have that,

<h3>The linear equation that best fits the data is y=-8.583x+475.215</h3>

Thus, option A is correct.
