Answer

  1. Points: A(3, -9) and B(-12, -6)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (-6 - (-9)) / (-12 - 3) = (3) / (-15) = -1/5
  2. Points: A(5, 14) and B(1, 6)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (6 - 14) / (1 - 5) = (-8) / (-4) = 2
  3. Points: A(-3, 14) and B(2, 9)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (9 - 14) / (2 - (-3)) = (-5) / (5) = -1
  4. Points: A(-4, -9) and B(0, -8)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (-8 - (-9)) / (0 - (-4)) = (1) / (4) = 1/4
  5. Points: A(4, 1) and B(6, -1)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (-1 - 1) / (6 - 4) = (-2) / (2) = -1
  6. Points: A(-11, 4) and B(-2, 4)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (4 - 4) / (-2 - (-11)) = (0) / (9) = 0
  7. Points: A(9, 15) and B(-6, 5)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (5 - 15) / (-6 - 9) = (-10) / (-15) = 2/3
  8. Points: A(-1, -9) and B(-5, -1)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (-1 - (-9)) / (-5 - (-1)) = (8) / (-4) = -2
  9. Points: A(-14, 16) and B(18, 0)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (0 - 16) / (18 - (-14)) = (-16) / (32) = -1/2
  10. Points: A(-1, -20) and B(-1, 1)
    Slope (m):
    m = (y2 - y1) / (x2 - x1) = (1 - (-20)) / (-1 - (-1)) = (21) / (0) = undefined
