Math Problem Statement

What is the slope of a line perpendicular to y = -8x + 12?

Solution

To solve this problem, we need to find the slope of a line that is perpendicular to the given line y=8x+12y = -8x + 12.

  1. Identify the slope of the given line: The equation of the given line is in slope-intercept form, y=mx+by = mx + b, where mm is the slope. For the given equation y=8x+12y = -8x + 12, the slope mm is 8-8.

  2. Determine the slope of the perpendicular line: For two lines to be perpendicular, the product of their slopes must be 1-1. If the slope of the original line is m1m_1, the slope of the perpendicular line m2m_2 is found using the relation: m1×m2=1m_1 \times m_2 = -1 Since the slope of the given line is 8-8, we can solve for m2m_2: 8×m2=1-8 \times m_2 = -1 Dividing both sides by 8-8: m2=18m_2 = \frac{1}{8}

Thus, the slope of the line perpendicular to y=8x+12y = -8x + 12 is 18\frac{1}{8}.
