Write y =1/8 x + 7 in standard form using integers.

1 answer

To convert the equation \( y = \frac{1}{8}x + 7 \) to standard form using integers, we want to eliminate the fraction and rearrange the equation into the form \( Ax + By = C \), where \( A \), \( B \), and \( C \) are integers.

  1. Start with the original equation: \[ y = \frac{1}{8}x + 7 \]

  2. Multiply every term by 8 to eliminate the fraction: \[ 8y = x + 56 \]

  3. Rearrange the equation to standard form by moving \( x \) to the left side: \[ -x + 8y = 56 \]

  4. To make the coefficient of \( x \) positive, we can multiply the entire equation by -1: \[ x - 8y = -56 \]

Now the equation \( x - 8y = -56 \) is in standard form with integers.

Thus, the final answer is: \[ x - 8y = -56 \]
