Question

M is the midpoint of segment GR. G has coordinates (11,-5) and M is (4,-4) Find the coordinates of R

Answer 1

Answer:

• (3, -3)

Step-by-step explanation:

Given:

• G = (11,-5)
• M = (4,-4)
• R = ?

Solution

• R(x, y)

As per midpoint formula;

• 4 = (11 + x)/2  ⇒ x + 11 = 8 ⇒ x = 3
• -4 = (-5 + y)/2 ⇒ y - 5 = -8 ⇒ y = -3
• R = (3, -3)
