Question 1126724: If m1 and m2 represent the slopes of two lines, determine if the lines are parallel, perpendicular, or neither.
7. m1 = 2 an m2 = 1/2
8. m1 = 2 and m2 = - 1/2
9. m1 = 2 and m2 = -2
10. m1 = 2 and m2 = 4/2
11. m1 = 0 and m2 = undefined Answer by math_helper(2461) (Show Source):
8. m1 = 2 and m2 = - 1/2
Perpendicular (when m1= -1 / m2, the lines are perpendicular)
9. m1 = 2 and m2 = -2
Neither
10. m1 = 2 and m2 = 4/2
Parallel (when m1 = m2, the lines are parallel)
11. m1 = 0 and m2 = undefined
Perpendicular (this is a special case, m2 undefined means that line is vertical, and m1=0 indicates that line is horizontal)
