Answer:

  • R = (-6, 14)

Step-by-step explanation:

Given

  • Segment RS and midpoint M(-1, 13)
  • S = (4, 12)
  • R = ?

Solution

Midpoint formula

  • x = (x1 + x2)/2 and  y = (y1 + y2)/2

Coordinates of point R

  • -1 = (4 + x)/2 ⇒ 4 + x = -2 ⇒ x = -6
  • 13 = (12 + y)/2 ⇒ 12 + y = 26 ⇒ y = 14
  • R = (-6, 14)
