GivenP(-7,2) is one endpoint of the line segment PQ and M(-5,6) is the midpoint of PQ, find the coordinates of the other endpoint Q.
Thanks alot in advance
If a and b are ordinate or abcissa of two points then mid point say c is given by
in your question,mid point is given.
So let us consider the abcissa first
hence the abcissa of the end point is -3.similarly you can find the ordinate of the end point.
