The incentre of the triangle formed by the links x=0, y=0 and 3x+4y=12 is at

In order to answer this question, we used the formula for the coordinates of a triangle's in-center when the lengths of its sides a, b, and c are known, as well as the coordinates of its vertices. The incentre is (1,1).

Two vertices of a triangle are (3,-2) and (-2,3) and its orthocentre is (-6,1). Then its third vertex is

 2x+y-4=0 and the x-y+7=0 are the equations that pass through the third vertex.

If in triangle , circumcenter  and orthocenter  then the co-ordinates of mid-point of side opposite to  is :

>>> The orthocenter, centroid and circumcenter of any triangle are collinear. And the centroid divides the distance from orthocenter to circumcenter in the ratio $2:1$.
>>> Also, the centroid $(G)$ divides the medians $(AD)$ in the ratio $2:1.$
>>> ∴D(h, k)=(1,​)

A triangle ABC with vertices A(-1,0), B(-2,3/4)&C(-3,-7/6) has its orthocentre H. Then the orthocentre of triangle BCH will be
