Transform the linear equation 4x−8y=24

to slope-intercept form.

1 answer

To transform the equation \( 4x - 8y = 24 \) into slope-intercept form, we need to isolate \( y \) on one side of the equation. The slope-intercept form is given by \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

Here are the steps to rearrange the equation:

  1. Start with the original equation: \[ 4x - 8y = 24 \]

  2. Subtract \( 4x \) from both sides: \[ -8y = -4x + 24 \]

  3. Divide every term by \(-8\) to solve for \( y \): \[ y = \frac{-4}{-8}x + \frac{24}{-8} \]

  4. Simplify the fractions: \[ y = \frac{1}{2}x - 3 \]

Now the equation is in the slope-intercept form \( y = mx + b \).

Thus, the final answer is: \[ y = \frac{1}{2}x - 3 \]
