A line of best fit expresses the relationship between the points.

**Explanation:**

It does not go through all the points but goes through most of them and it is like a hardrawn curve

**Answer:**

what is the question name

**Answer:**

**B**. The wind is blowing at 20 m/s. The airplane is flying with the wind at 130 m/s.

**Explanation:**

From Physics we get that resultant velocity of an airplane is the sum of an absolute velocity and a relative velocity, that is:

**(Eq. 1)**

Where:

- Wind velocity, measured in meters per second.

- Airplance velocity relative to wind, measured in meters per second.

- Airplane velocity, measured in meters per second.

If we assume that (The airplane flies with the wind), , then the resultant velocity of the airplane is:

Therefore, correct answer is **B**.
