Find the slope and y - intercept of the following lines.
`y=3x+4`

Answer

To find the slope and y-intercept of the line given by the equation \( y = 3x + 4 \), we can follow these steps:

### Step 1: Identify the Standard Form
The equation of a straight line can be expressed in the slope-intercept form, which is:
\[ y = mx + c \]
where:
- \( m \) is the slope of the line,
- \( c \) is the y-intercept.

### Step 2: Compare with the Given Equation
We have the equation:
\[ y = 3x + 4 \]

### Step 3: Identify the Slope
In the equation \( y = 3x + 4 \), the coefficient of \( x \) (which is \( 3 \)) represents the slope \( m \).
Thus, we can conclude:
\[ m = 3 \]

### Step 4: Identify the Y-Intercept
The constant term (which is \( 4 \)) represents the y-intercept \( c \).
Thus, we can conclude:
\[ c = 4 \]

### Final Answer
- The slope of the line is \( 3 \).
- The y-intercept of the line is \( 4 \).
