The midpoint formula is Midpoint = (x1+x2)/2 , (y1+y2)/2

Since you know the midpoint, you can sub in one of the coordinates' x number.

K: (6, -12)

6 + x / 2 = 0

Solve for x.

This will be the x coordinate of your missing point.

Do the same for y.

K: (6, -12)

-12 + x / 2 = -7

Solve for y.

Your result for L is (x,y).

If you need help solving for the variable, let me know.

Btw, when I write / 2, it is all over 2 (aka division, which means multiply by that number on both sides).
