The good approximation of the line of best fit f(x) ≈ 1.8x − 5.4 for x when f(x) = 30 is; 20

How to Interprete Line of Best Fit?

We are told that the equation that represents the line of best fit is;

f(x) ≈ 1.8x − 5.4

Now, we want to find the best approximation for f(x) = 30. Thus;

f(x) = 30 ≈ 1.8x − 5.4

Add 5.4 to both sides to get;

1.8x - 5.4 + 5.4 = 35.4

x = 35.4/1.8

x = 19.7

x ≈ 20
