Answer: Neither
Step-by-step explanation: To determine whether two lines are parallel, perpendicular, or neither, we can compare their slopes. Parallel lines have the same slope, and perpendicular lines have slopes that are negative reciprocals of each other.
The slope of a vertical line is undefined, and the slope of a horizontal line is 0.
The equation y = -4 represents a horizontal line, and the equation x = 8 represents a vertical line.
Since the slopes of the two lines are undefined and 0, respectively, the lines are neither parallel nor perpendicular.
