b. what score can emmanuel expect to get after 10 weeks?

Explanation:

Step1: Identify best-fit line equation

The given best-fit line is $y = -3.1x + 115.1$, where $x$ = week number, $y$ = golf score.

Step2: Substitute $x=10$ into equation

Substitute $x=10$ to find the predicted score:
$y = -3.1(10) + 115.1$

Step3: Calculate the result

First compute the product: $-3.1\times10 = -31$, then add to 115.1:
$y = -31 + 115.1 = 84.1$

Answer:

84.1
