Answer:

The coordinates of point S are (12, -18).

Explanation:

The midpoint formula is given by:

M = (x1 + x2) / 2, (y1 + y2) / 2, where

  • M are the coordinates of the midpoint,
  • (x1, y1) is one endpoint,
  • and (x2, y2) is another endpoint.

We can find the x and y-coordinate of point S and then combine them at the end.

Finding the x-coordinate of point S:

We know that:

  • the x-coordinate of point T is 0,
  • and the x-coordinate of the midpoint ST is 6.

Now, we can find the x-coordinate of point S by substituting 0 for x1 and 6 for M in the midpoint formula:

(6 = (0 + x2) / 2) * 2

(12 = 0 + x2)

12 = x2

Thus, the x-coordinate of point S is 12.

Finding the y-coordinate of point S:

We also know that:

  • the y-coordinate of point T is 2,
  • and the y-coordinate of the midpoint ST is -8.

Now, we can find the y-coordinate of point S by substituting 2 for y1 and -8 for M in the midpoint formula:

(-8 = 2 + y2) / 2) * 2

(-16 = 2 + y2) - 2

-18 = y2

Thus, the y-coordinate of point S is -18.

Combining the coordinates of point S:

Therefore, the coordinates of point S are (12, -18).
