Find the other endpoint of the line segment with the given endpoint and midpoint Endpoint: (3,5)
Midpoint: (7, -2)

The other endpoint is (11,-9)

Step-by-step explanation:

Midpoint Formula

We already know the another endpoint which is (3,5). We substitute x = 3 and y = 5 in the formula. You can substitute in x1, x2 or y1, y2. I'll substitute in first x-term and first y-term instead.

Because sum of two x-coordinate (along with y-coordinate) divided by two must equal to the midpoint (Let's say that you get the value of midpoint when using midpoint formula.)

Solve the equation for both terms.

Cancel the denominator by multiplying the whole equation by 2.

Isolate x-term and y-term.

Therefore, when x = 11, y = -9. We can write in ordered pair as (11,-9). The ordered pair (11,-9) is our other endpoint of the line segment. This can be proved by using the distance formula between midpoint and endpoints.

Note: The distance of (3,5) and (7,-2) must equal to the distance of (11,-9) and (7,-2)
