Important Points on Areas of Parallelograms and Triangles

If the lines 2x-y=8,x-2y=17 and line L=0 form an isoceles triangle,then slope of line L can be

If the circumcentre of a triangle lies at the point (a, a) and the centroid is the mid - point of the line joining the points (2a+3, a+4) and (a-4, 2a-3) , then the orthocentre of the triangle lies on the line

Two straight lines pass through the fixed points (+-a,0) and have slopes whose products is p>0 show that the locus of the points of intersection of the lines is a hyperbola.

Centroid OF triangle & question based on centroid || Important points OF straight line

The slope of a line is double of the slope of another line.If tangent of the angle between them is them is (1)/(3) find the slopes of the lines.
