" The lines "|x+my+n=0,mx+ny+1=0" and "nx+1y+m=0" are concurrent if (where "I!=m!=n)

The lines lx+my+n=0,mx+ny+l=0 and nx+ly+m=0 are concurrent if (where l!=m!=n)

If the lines lx + my + n = 0, mx + ny + l = 0 and nx + ly + m = 0 are concurrent then

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

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

The lines x+y-1=0,(m-1)x+(m^(2)-7)y-5=0 and (m-2)x+(2m-5)y=0 are concurrent for three values of m concurrent for one value of m concurrent for no value of m parallel for m=3.

Find the value of m for which the lines 4x -3y - 1 = 0, 3x - 4y + 1 = 0 and mx - 7y + 3 = 0 are concurrent.

The lines x+y-1=0,(m-1)x+(m^(2)-7)y-5=0 and (m-2)x+(2m-5)y=0 are concurrent for three values of m concurrent for no value of m parallel for one value of m parallel for two value of m

The lines x+y-1=0,(m-1)x+(m^2-7)y-5=0, and (m-2)x+(2m-5)y=0 are concurrent for three values of m concurrent for no value of m parallel for one value of m parallel for two value of m

Number of integral values of m for which lines x+y+1=0,mx-m^(2)y+3=0 and 2mx-(2m-1)y+(3m+2)=0 are concurrent
