1 answer

To determine which lines are perpendicular to each other, we need to look at the slopes of the lines given by their equations.

  1. Identify the slopes:

    • Line A: \( y = 2x - 3 \) (slope = 2)
    • Line B: \( y = 2x + 5 \) (slope = 2)
    • Line C: \( y = -12x - 2 \) (slope = -12)
    • Line D: \( y = 12x + 2 \) (slope = 12)
  2. Check for perpendicularity:

    • Two lines are perpendicular if the product of their slopes is -1 (i.e., if one slope is the negative reciprocal of the other).

    • Line A and Line B:

      • Slopes: 2 and 2
      • \( 2 \times 2 = 4 \) (not perpendicular)
    • Line A and Line C:

      • Slopes: 2 and -12
      • \( 2 \times -12 = -24 \) (not perpendicular)
    • Line C and Line D:

      • Slopes: -12 and 12
      • \( -12 \times 12 = -144 \) (not perpendicular)
    • Line B and Line D:

      • Slopes: 2 and 12
      • \( 2 \times 12 = 24 \) (not perpendicular)
  3. Conclusion: Since none of the pairs of lines have slopes that are negative reciprocals of each other, there are no perpendicular lines among the given options.

Thus, the correct answer is: None of the statements are true regarding perpendicular lines.
