The length L (in centimetre) of a copper rod is a linear function of its Celsius temperature C. In an experiment, if `L = 124. 942`when `C = 20`and `L= 125. 134`when `C = 110`, express L in terms of C.

Explanation

To express the length \( L \) of a copper rod in terms of its Celsius temperature \( C \), we can follow these steps:

### Step 1: Identify the points
We have two points based on the given data:
- Point 1: \( (C_1, L_1) = (20, 124.942) \)
- Point 2: \( (C_2, L_2) = (110, 125.134) \)

### Step 2: Calculate the slope (m)
