The task is to rewrite the given equations of lines from slope-intercept form ( \( y = mx + b \) ) into standard form ( \( Ax + By = C \), where \( A \), \( B \), and \( C \) are integers, and \( A \) is typically positive).

Let's work through the equations step by step:

### 11. \( y = \frac{1}{2}x + 3 \)
- Subtract \( \frac{1}{2}x \) from both sides:
  \[ -\frac{1}{2}x + y = 3 \]
- Multiply through by 2 to eliminate the fraction:
  \[ -x + 2y = 6 \]
- Multiply by -1 to make \( A \) positive:
  \[ x - 2y = -6 \]

**Standard form: \( x - 2y = -6 \)**

---

### 12. \( y = -\frac{4}{3}x - 5 \)
- Add \( \frac{4}{3}x \) to both sides:
  \[ \frac{4}{3}x + y = -5 \]
- Multiply through by 3 to eliminate the fraction:
  \[ 4x + 3y = -15 \]

**Standard form: \( 4x + 3y = -15 \)**

---

### 13. \( y = -\frac{7}{3}x + 3 \)
- Add \( \frac{7}{3}x \) to both sides:
  \[ \frac{7}{3}x + y = 3 \]
- Multiply through by 3 to eliminate the fraction:
  \[ 7x + 3y = 9 \]

**Standard form: \( 7x + 3y = 9 \)**

---

### 14. \( y = \frac{11}{5}x - 5 \)
- Subtract \( \frac{11}{5}x \) from both sides:
  \[ -\frac{11}{5}x + y = -5 \]
- Multiply through by 5 to eliminate the fraction:
  \[ -11x + 5y = -25 \]
- Multiply by -1 to make \( A \) positive:
  \[ 11x - 5y = 25 \]

**Standard form: \( 11x - 5y = 25 \)**

---

2. What is the general rule for eliminating fractions in linear equations?
3. Can standard form equations have fractional coefficients?
4. How do you verify if a linear equation is in standard form?
5. Why is it preferred to have a positive coefficient for \( A \) in the standard form?

**Tip:** Always check the final standard form equation to ensure that all coefficients are integers and the coefficient of \( x \) is positive if possible.

Write the standard form of the equation of each line. Given equations in slope-intercept form (y = mx + b) include: 1. y = 1/2x + 3, 2. y = -4/3x - 5, 3. y = -7/3x + 3, 4. y = 11/5x - 5.
