Question

The coordinates of point T are (0,5). The midpoint of ST is (5,-2). Find the coordinates of point S.​

Answer 1

Answer:

(10, -9)

Step-by-step explanation:

Xs = 5 -(0-5) = 5+5 = 10

Ys = -2 -(5-(-2)) = -2 - 7 = -9

so, the coordinates of point S => (10, -9)

Answer 2

Answer:

• S(10, -9)

Step-by-step explanation:

Use midpoint formula and assume S(x, y):

• (0 + x)/2 = 5 ⇒ x / 2 = 5 ⇒ x = 10
• (5 + y)/2 = -2 ⇒ 5 + y = -4 ⇒ y = -4 - 5 ⇒ y = -9
