Answer:
(10, 2)
Step-by-step explanation:
To get from the given endpoint to the midpoint, 6 was added to x and 2 was added to y. As per the definition of a midpoint, the resulting two line segments will be congruent (first endpoint and midpoint congruent to midpoint and second endpoint). Use the same formula (x + 6, y + 2) to find the second endpoint (use the x and y of the midpoint):
(x + 6, y + 2)
(4 + 6, 0 +2)
(10, 2)
