• slope of line AB = ((the y coordinate of point B) - (the y coordinate of point A)) / ((the x coordinate of point B) - (the x coordinate of point A))
• slope of line AB = ((the y coordinate of point B) - (the y coordinate of point A)) / ((the x coordinate of point B) - (the x coordinate of point A))
• if M is the midpoint of line AB, then the x coordinate of point M = ((the x coordinate of point A) + (the x coordinate of point B)) / 2

• if the following are true:

  • a = x
  • c = y
  • s = (a + c) / m

  then s = (x + y) / m

• if x = (0 + (a ⋅ 2)) / 2, then x = a

• if M is the midpoint of line AB, then the y coordinate of point M = ((the y coordinate of point A) + (the y coordinate of point B)) / 2

• if the following are true:

  • a = x
  • c = y
  • s = (a + c) / m

  then s = (x + y) / m

• if x = (0 + (a ⋅ 2)) / 2, then x = a

• if M is the midpoint of line AB, then the x coordinate of point M = ((the x coordinate of point A) + (the x coordinate of point B)) / 2

• if the following are true:

  • a = x
  • c = y
  • s = (a + c) / m

  then s = (x + y) / m

• if x = ((b ⋅ 2) + (a ⋅ 2)) / 2, then x = b + a

• if M is the midpoint of line AB, then the y coordinate of point M = ((the y coordinate of point A) + (the y coordinate of point B)) / 2

• if the following are true:

  • a = x
  • c = y
  • s = (a + c) / m

  then s = (x + y) / m

• if x = (0 + (a ⋅ 2)) / 2, then x = a

• if the following are true:

  • f = (a - b) / (c - d)
  • a = w
  • b = x
  • c = y
  • d = z

  then f = (w - x) / (y - z)

• if b > 0, then (0 - 0) / ((b ⋅ 2) - 0) = 0

• if the following are true:

  • a = b
  • b = c

  then a = c

• if the following are true:

  • f = (a - b) / (c - d)
  • a = w
  • b = x
  • c = y
  • d = z

  then f = (w - x) / (y - z)

• if b > 0, then (c - c) / ((b + a) - a) = 0

• if the following are true:

  • a = b
  • b = c

  then a = c

• if the following are true:

  • a = c
  • b = c

  then a = b

• if slope of line AB = slope of line CD, then AB || CD
