Answer: C (29,-9). Explanation: Two the endpoint of the line, find the difference between the midpoint’s x and y and the end point’s x and y, and you add that to the midpoint.
The other endpoint of the given line segment is (29, -9).
If O(x, y) is the midpoint between the line segment AB with end points A(x₁, y₁) and B(x₂, y₂). The coordinate of the midpoint is:
x = (x₁ + x₂)/2; y = (y₁ + y₂)/2
Let A(x, y) be the other end point. Since one end point is (-9, 9) and Midpoint (10,0), hence:
10 = (x + (-9))/2
20 = x - 9
x = 29
0 = (y + 9)/2
0 = y + 9
y = -9
Therefore the other endpoint of the given line segment is (29, -9).
