If the line `y=mx` meets the lines `x+2y-1=0` and `2x-y+3=0` at the same point, then m is equal to

The line y=(3x)/(4) meets the lines x-y+1-0 and 2x-y=5 at A and B respectively.Coordinates of P on y=(3x)/(4) such that PA*PB=25 .

The lines 3x-4y=9 and y=0 meet at :

If the lines 3x + 4y + 1 = 0 , 5x+lambday+3=0 and 2x+y-1=0 are concurrent, then lambda is equal to-

If the line y = mx + 4 is tangent to x^(2) + y^(2) = 4 and y^(2) = 4ax then a is (a gt 0) equal to :
