To determine the relationships between the pairs of lines (whether they are parallel, perpendicular, or intersecting), we need to analyze their slopes.

  1. First Equation: y − 6 = 14(x + 2)

    • Rearranging this to slope-intercept form (y = mx + b):
    • y = 14x + 28 + 6
    • y = 14x + 34
    • Slope = 14
  2. Second Equation: y = −4x − 10

    • Slope = -4
  3. Third Equation: y = −23x + 7

    • Slope = -23
  4. Fourth Equation: -2x - 3y = 12

    • Rearranging to slope-intercept form:
    • 3y = -2x - 12
    • y = (-2/3)x - 4
    • Slope = -2/3
  5. Fifth Equation: 2x - y = 7

    • Rearranging to slope-intercept form:
    • y = 2x - 7
    • Slope = 2
  6. Sixth Equation: 3x - 4y = -8

    • Rearranging to slope-intercept form:
    • 4y = 3x + 8
    • y = (3/4)x + 2
    • Slope = 3/4
