**Question:**

Find an equation of the line in standard form with an x-intercept of 2 and a y-intercept of 4.

**Explanation:**

To find the equation of a line in standard form, given the x-intercept and y-intercept:

1. **Identify the intercepts**:
   - The x-intercept is the point (2, 0).
   - The y-intercept is the point (0, 4).

2. **Use the intercepts to write the equation**:
   - A line's equation in standard form is \( Ax + By = C \).
   - Use the intercepts to derive the equation:
     - Plug x = 2 into the equation and y = 0, which gives \( 2A = C \).
     - Plug x = 0 into the equation and y = 4, which gives \( 4B = C \).

3. **Solve for coefficients A, B, and C**:
   - From these equations, solve for values that will satisfy both equations, typically \( A = -2 \), \( B = -1 \), and \( C = -4 \). The exact form may vary.

4. **Equation**:
   - Substitute back into the equation to verify: \(-2x - y = -4\).

This complex technique of using intercepts and solving equations helps in understanding and formulating the equation of a line in standard form.
