Question
**Classify the Lines**

Line 1 has the equation \( y = 3x + 5 \).

Line 2 has the equation \( y - 4 = 3(x - 2) \).

**Options:**

- ○ intersecting but not perpendicular
- ○ coinciding
- ○ perpendicular
- ○ parallel

To determine the relationship between these two lines, solve for the equation of Line 2:

1. Expand Line 2's equation:  
   \( y - 4 = 3(x - 2) \)  
   \( y - 4 = 3x - 6 \)  
   Add 4 to both sides:  
   \( y = 3x - 2 \)

2. Compare the equations:
   - Line 1: \( y = 3x + 5 \)
   - Line 2: \( y = 3x - 2 \)

Since both lines have the same slope of 3 and different y-intercepts, they are parallel.
