Question

a line of best fit is drawn for the set of points shown on the graph. which point is an approximate extrapolation for x = 30 from the line of best fit? (23, 30) (30, 38) (44, 30) (30, 72)

Explanation:

Step1: Identify the linear regression equation

The linear regression equation given is \( y \approx 1.14x + 3.805 \).

Step2: Substitute \( x = 30 \) into the equation

We substitute \( x = 30 \) into the equation \( y = 1.14x + 3.805 \) to find the corresponding \( y \)-value.

So, when \( x = 30 \), \( y \approx 38 \).

Answer:

(30, 38)
