Find the equations of the lines , whose :
slope = 3 and y- intercept =4

Answer

To find the equation of the line with a given slope and y-intercept, we can use the slope-intercept form of a linear equation, which is:

\[ y = mx + c \]

where:
- \( m \) is the slope of the line,
- \( c \) is the y-intercept.

### Step-by-Step Solution:

1. **Identify the given values**:
- Slope (\( m \)) = 3
- Y-intercept (\( c \)) = 4

2. **Substitute the values into the slope-intercept form**:
- We replace \( m \) with 3 and \( c \) with 4 in the equation \( y = mx + c \).
- This gives us:
\[ y = 3x + 4 \]

3. **Write the final equation**:
- The equation of the line is:
\[ y = 3x + 4 \]

### Final Answer:
The equation of the line with a slope of 3 and a y-intercept of 4 is:
\[ y = 3x + 4 \]
