Question

The coordinates of point 7 are given. The midpoint of ST is (5. - 8). Find the coordinates of point S.

9. T(10, 18)

Answer 1

S(0, 2)

Explanation:

Midpoint Formula:
`((x_1+x_2)/(2) ,(y_1+y_2)/(2) )`

Step 1: Plug in known variables

5 = (10 + x)/2

-8 = (18 + y)/2

Step 2: Solve

10 = 10 + x

x = 0

-16 = 18 + y

y = 2

Step 3: Write coordinates

(0, 2)
