To find the other endpoint, you effectively reverse this process. A frequent mistake is forgetting to multiply the midpoint coordinate by 2 before subtracting the endpoint value, which leads to incorrect results.

This dual calculation handles the horizontal and vertical positions independently, simplifying the complex geometry into manageable arithmetic. Common Mistakes to Avoid Errors often occur when handling the signs of the numbers or the order of operations.
If you know the coordinates of the midpoint and one endpoint, you can leverage the midpoint formula to reverse-engineer the location of the other endpoint. This requires isolating \(x_2\) and \(y_2\) in the equation, resulting in the derived formulas \(x_2 = 2M_x - x_1\) and \(y_2 = 2M_y - y_1\).

Therefore, the missing endpoint is located at \((3, -1)\). To find the x-coordinate of the missing endpoint, you calculate \(2(5) - 7\), which equals 3.
