If I,m, n are in A.P then the lines represented by `lx + my+n=0` are concurrent at the point

If l,m,n are in A.P then the liens represented by lx+my+n=0 are concurrent at the point

If a,b,c are in A.P then the lines represented by ax+by+c=0 are concurrent at the point

If l, m, n are in AP, then the line lx+my+n=0 will always pass through the point

If l, m, n are in AP, then the line lx+my+n=0 will always pass through the point

Lines p ,\ q\ a n d\ r are concurrent. Also, lines p ,\ r\ a n d\ s are concurrent. Draw a figure and state whether lines p ,\ q ,\ r\ a n d\ s are concurrent or not.

Show that the lines lx+my+n=0, mx+ny+l=0 and nx+ly+m=0 are concurrent if l+m+n=0

If 9l^(2)+16m^(2)-n^(2)-24lm=0 then the family of straight lines lx+my+n=0 are concurrent.The points of concurrency are

If lx + my + n = 0 , where l, m, n are variables, is the equation of a variable line and l, m, n are connected by the relation al+bm+cn=0 where a, b, c are constants. Show that the line passes through a fixed point.

If lx + my + n = 0 , where l, m, n are variables, is the equation of a variable line and l, m, n are connected by the relation al+bm+cn=0 where a, b, c are constants. Show that the line passes through a fixed point.
