Question

Use the line of best fit of the given table to find the value of y when x is 11? y = 2.162 + 6.6 remember to round to the nearest whole number!!! Pic attached below​

Answer 1

Rounding to the nearest whole number, when x = 11, y = 30.

How to estimate the value when x = 11?

Here we know that the line of best fit is:

y = 2.16*x + 6.6

To estimate the value of y when x = 11, we only need to evaluate the equation in x = 11, then we will get:

y = 2.16*11 + 6.6

y = 30.36

Rounding to the nearest whole number we get 30.
