To find the equation of the line passing through the point \( (-8, -8) \) and parallel to the line represented by \( -x + 8y = 48 \), we first need to determine the slope of the given line. We can rewrite that equation in slope-intercept form \( y = mx + b \): 1. Rearranging the given line: \(-x + 8y = 48\) \(8y = x + 48\) \(y = \frac{1}{8}x + 6\) So, the slope \( m \) of the given line is \( \frac{1}{8} \). Since parallel lines have the same slope, the slope of our new line is also \( \frac{1}{8} \). (a) Using the point-slope form of the line equation, \( y - y_1 = m(x - x_1) \), where \( (x_1, y_1) = (-8, -8) \): \[ y + 8 = \frac{1}{8}(x + 8) \] Now, simplify this: \[ y + 8 = \frac{1}{8}x + 1 \] \[ y = \frac{1}{8}x + 1 - 8 \] \[ y = \frac{1}{8}x - 7 \] So, in slope-intercept form, the equation is: \[ y = \frac{1}{8}x - 7 \] (b) Now, to convert this into standard form \( Ax + By = C \): Start with the slope-intercept form: \[ y = \frac{1}{8}x - 7 \] Multiply through by 8 to eliminate the fraction: \[ 8y = x - 56 \] Now, rearranging gives: \[ -x + 8y = -56 \] To further align with standard form (where \( A \) is positive): \[ x - 8y = 56 \] So, in standard form, the equation is: \[ x - 8y = 56 \]
