To determine whether the lines represented by the equations \( y = \frac{1}{4}x - 2 \) and \( y = -4x - 1 \) are parallel, perpendicular, or neither, we need to analyze their slopes.
-
Identify the slope of each line:
- For the first equation \( y = \frac{1}{4}x - 2 \), the slope \( m_1 \) is \( \frac{1}{4} \).
- For the second equation \( y = -4x - 1 \), the slope \( m_2 \) is \( -4 \).
-
Determine if the lines are parallel, perpendicular, or neither:
- Lines are parallel if their slopes are equal: \( m_1 = m_2 \).
- Lines are perpendicular if the product of their slopes is \(-1\): \( m_1 \cdot m_2 = -1 \).
Now, calculate the product of the slopes:
\[ m_1 \cdot m_2 = \frac{1}{4} \cdot (-4) = -1 \]
Since the product of the slopes is \(-1\), the lines are perpendicular.
