The midpoint of the line segment joining $(1, 1)$ and $(3, 3)$ is:

If the points are $(12, 10)$ and $(0, 8)$, then the midpoint of the line segment joining these two points is $\ldots \ldots \ldots \ldots$

$A$ point $(4,4)$ divides the line segment joining $A(2,6)$ and $B(6,2)$ from $A$,then the ratio of division is $\ldots \ldots \ldots \ldots .$

Find the points of trisection of the line segment joining $(7, 5)$ and $(-2, -1)$.

$A$ line intersects the $y$-axis and $x$-axis at the points $P$ and $Q$,respectively. If $(2, -5)$ is the mid-point of $PQ$,then the coordinates of $P$ and $Q$ are,respectively:

Let $A(4,2)$,$B(6,5)$,and $C(1,4)$ be the vertices of $\Delta ABC$. The median from $A$ meets $BC$ at $D$. Find the coordinates of the point $D$.
