This worksheet helps students practice identifying straight and curved lines.

Problem Description:

The task is to identify whether each of the given lines in the worksheet is straight (horizontal, vertical, or slanting) or curved. The lines are numbered from 1 to 15, and we need to classify them accordingly.

---

Solution Approach:

1. Straight Line: A straight line has no curves or bends. It can be horizontal, vertical, or slanting.
- Horizontal: Runs left to right (parallel to the x-axis).
- Vertical: Runs up and down (parallel to the y-axis).
- Slanting: Runs diagonally at an angle.

2. Curved Line: A curved line has a bend or curve in it. It does not follow a straight path.

3. Classification:
- Carefully observe each line and determine if it is straight or curved based on the above definitions.

Step-by-Step Analysis:

#### Line 1:
- The line is diagonal (slanting).
- Classification: Straight (slanting).

#### Line 2:
- The line has a bend or curve.
- Classification: Curved.

#### Line 3:
- The line is vertical.
- Classification: Straight (vertical).

#### Line 4:
- The line is horizontal.
- Classification: Straight (horizontal).

#### Line 5:
- The line is diagonal (slanting).
- Classification: Straight (slanting).

#### Line 6:
- The line has a bend or curve.
- Classification: Curved.

#### Line 7:
- The line has a bend or curve.
- Classification: Curved.

#### Line 8:
- The line is vertical.
- Classification: Straight (vertical).

#### Line 9:
- The line is diagonal (slanting).
- Classification: Straight (slanting).

#### Line 10:
- The line has a bend or curve.
- Classification: Curved.

#### Line 11:
- The line is horizontal.
- Classification: Straight (horizontal).

#### Line 12:
- The line has a bend or curve.
- Classification: Curved.

#### Line 13:
- The line is vertical.
- Classification: Straight (vertical).

#### Line 14:
- The line is diagonal (slanting).
- Classification: Straight (slanting).

#### Line 15:
- The line has a bend or curve.
- Classification: Curved.

Final Answer:

\[
\boxed{
\begin{array}{ccc}
1. \text{Straight (slanting)} & 2. \text{Curved} & 3. \text{Straight (vertical)} \\
4. \text{Straight (horizontal)} & 5. \text{Straight (slanting)} & 6. \text{Curved} \\
7. \text{Curved} & 8. \text{Straight (vertical)} & 9. \text{Straight (slanting)} \\
10. \text{Curved} & 11. \text{Straight (horizontal)} & 12. \text{Curved} \\
13. \text{Straight (vertical)} & 14. \text{Straight (slanting)} & 15. \text{Curved} \\
\end{array}
