How to find EF on a line segment with number 2.6 and 3.5

To find the length of the line segment \( EF \) when you have two points on a number line, such as \( E = 2.6 \) and \( F = 3.5 \), you simply find the absolute difference between these two points. 

### Step-by-Step Solution

1. **Identify the coordinates of points \( E \) and \( F \):**
   - Point \( E \) has a coordinate of \( 2.6 \).
   - Point \( F \) has a coordinate of \( 3.5 \).

2. **Apply the formula for the length of a segment on a number line:**
   The length of a segment \( EF \) on a number line is given by the absolute difference between the coordinates of \( E \) and \( F \):

   \[
   EF = | F - E |
   \]

3. **Substitute the values:**

   \[
   EF = |3.5 - 2.6|
   \]

4. **Calculate the difference:**

   \[
   EF = |0.9| = 0.9
   \]

### Conclusion

The measure of segment \( EF \) is \( 0.9 \) units.
