The correct Answer is:
To find the value of \( p \) when the equation of the straight line \( 2x + 5y = 4 \) is transformed after shifting the origin to the point \( (3, 3) \), we can follow these steps: ### Step-by-step Solution: 1. **Identify the Original Equation**: The original equation of the line is given as: \[ 2x + 5y = 4 \] 2. **Shift the Origin**: When the origin is shifted from \( (0, 0) \) to \( (3, 3) \), we need to replace \( x \) and \( y \) in the equation with \( x' \) and \( y' \) where: \[ x' = x - 3 \quad \text{and} \quad y' = y - 3 \] Thus, we can express \( x \) and \( y \) in terms of \( x' \) and \( y' \): \[ x = x' + 3 \quad \text{and} \quad y = y' + 3 \] 3. **Substitute into the Original Equation**: Substitute \( x \) and \( y \) into the original equation: \[ 2(x' + 3) + 5(y' + 3) = 4 \] 4. **Expand the Equation**: Expanding the equation gives: \[ 2x' + 6 + 5y' + 15 = 4 \] 5. **Combine Like Terms**: Combine the constant terms: \[ 2x' + 5y' + 21 = 4 \] 6. **Rearrange the Equation**: Rearranging the equation to isolate the terms involving \( x' \) and \( y' \): \[ 2x' + 5y' = 4 - 21 \] \[ 2x' + 5y' = -17 \] 7. **Identify the New Value of \( p \)**: The new equation after shifting the origin is: \[ 2x' + 5y' = p \] From our rearranged equation, we see that: \[ p = -17 \] ### Final Answer: Thus, the value of \( p \) is: \[ \boxed{-17} \]
