1. Line g has an undefined slope. If Line k contains the point (3, 8) and is parallel to Line g, what must be the x-coordinates of the other points that lie on the line? A. 0
B. 3
C. 8
D. 11
2. If line p has a slope of zero, and line m has an undefined slope, what can you conclude about line p and line m?
A. Line p is a vertical line and line m is a horizontal line therefore the two lines are perpendicular.
B. Line p is a horizontal line and line m is a vertical line therefore the two lines are perpendicular.
C. Line p and line m are both vertical lines therefore the two lines are parallel.
D. Line p and line m are both horizontal lines therefore the two lines are parallel.
3. The lines y = 8 and y = -8 are:
A. Parallel because they both have an undefined slope.
B. Perpendicular because their slopes are negative reciprocals.
C. Parallel because they both have a slope of 0.
D. Neither parallel nor perpendicular because they have different slopes.
. Write the equation of the line PERPENDICULAR to x = 7 passing through the point

A. (-2, 6).
B. x = -2
C. y = 6
D. y = 7x + 6
E. Y = -1/7X + 6
