15x − 10y = –7

1 answer

To solve the equation \( 15x - 10y = -7 \) for \( y \), we can rearrange it into the slope-intercept form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

  1. Start with the original equation: \[ 15x - 10y = -7 \]

  2. Isolate \( -10y \) by moving \( 15x \) to the right side: \[ -10y = -15x - 7 \]

  3. Divide each term by \(-10\): \[ y = \frac{15x}{10} + \frac{7}{10} \]

  4. Simplify the fractions: \[ y = \frac{3}{2}x + \frac{7}{10} \]

So, the equation in slope-intercept form is: \[ y = \frac{3}{2}x + \frac{7}{10} \]
