Given a midpoint and a coordinate work out the position of the other coordinate, where at least one value is negative and at least one is a non-integer Here are two points and their midpoint.
What should replace the triangle? ![The image is a set of axes with three points marked. One point is (1,7). The midpoint is (-1, 0.5). The third point is given as (star, triangle), so the triangle is the y value of the point.]() \( \Delta=-6.5 \)

Believes midpoint calculation is just half of the difference
