If the line `x = a + m, y = -2` and `y = mx` are concurrent, then least value of `|a|` is

If the lines y=x+1 , y=2x and y=kx+3 are concurrent find the value of 'k' .

If the lines ax+y=0,x+ay+2=0 and x+y+a=0 (a in R) are concurrent lines,then sum of all possible value(s) of a is

If the lines y=x+3 and y= 3x+1 are equally inclined to the line y= mx+4 then the value of m is

If the lines 2a" "+" "y" "" "3" "=" "0 , 5x" "+" "k y" "" "3" "=" "0 and 3x" "" "y" "" "2" "=" "0 are concurrent, find the value of k.

If the lines y=3x+1 and 2y=x+3 are equally inclined to the line y=mx+4, find the value of m.

If the intercept made on the line y=mx by the lines x=2 and x=5 is less then 5, then the range of m is

(i) Find the value of 'a' if the lines 3x-2y+8=0 , 2x+y+3=0 and ax+3y+11=0 are concurrent. (ii) If the lines y=m_(1)x+c_(1) , y=m_(2)x+c_(2) and y=m_(3)x+c_(3) meet at point then shown that : c_(1)(m_(2)-m_(3))+c_(2)(m_(3)-m_(1))+c_(3)(m_(1)-m_(2))=0
