Find the slope of the line that is a) parallel and b) perpendicular to the given line.

1. x= -8

2. y=10

To find the slope of a line, we need to know the equation of the line in either slope-intercept form (y = mx + b) or standard form (Ax + By = C). However, the given lines x = -8 and y = 10 are not in either of these forms. Therefore, we cannot directly determine the slope of these lines.

For a line with an equation in the form x = a, where a is a constant, the line is vertical and parallel lines have the same slope. Since the line x = -8 is vertical, it does not have a slope. Therefore, any line that is parallel to x = -8 will also be vertical and have no defined slope.

For a line with an equation in the form y = b, where b is a constant, the line is horizontal and perpendicular lines have slopes that are negative reciprocals of each other. Since the line y = 10 is horizontal, it has a slope of 0. Therefore, any line that is perpendicular to y = 10 will be vertical and not have a defined slope.
