Beyond the Answer

The slope of the given line \( y = 8x - 9 \) is 8. Lines that are parallel share the same slope, so the slope of a line parallel to this one will also be 8. To find the slope of a line that is perpendicular, we take the negative reciprocal of the slope of the original line. Since the slope of the given line is 8, the slope of a line perpendicular to it is \( -\frac{1}{8} \). Slope of a parallel line: 8 Slope of a perpendicular line: \(-\frac{1}{8}\)
