Answer:

  • 1. Perpendicular
  • 2. Neither
  • 3.  Parallel

Step-by-step explanation:

Finding slopes of the lines to determine their relationship

1. J(1, 9), K(7, 4), L(8, 13), M(-2, 1)

Slope of JK

  • m = (4-9)/(7-1) = -5/6

Slope of LM

  • m = (1-13)/(-2-8) = -12/-10 = 6/5

These lines are perpendicular as slopes are negative reciprocal

2 J(13, -5), K(2, 6), L(-1, -5), M(-4, -2)

Slope of JK

  • m = (6-(-5))/(2-13) = 11/(-11) = -1

Slope of LM

  • m = (-1-(-5))/(-4-(-1)) = 4/(-3) = -4/3

Lines are neither parallel nor perpendicular

3. J(-10, -7), K(-4, 1), L(-3, 2), M(-6, -2)

Slope of JK

  • m = (1-(-7))/(-4-(-10)) = 8/6 = 4/3

Slope of LM

  • m = (-2-2)/(-6-(-3)) = -4/-3 = 4/3

These lines are parallel as slopes are same

Answer:

1. Perpendicular

2. Neither

3.  Parallel
