In the figure, L1 and L2 are parallel lines. The correct relationship between angles y and x is:
Three lines given by L1:a1 x+b1 y+c1=0,L2:a2 x+b2 y+c2=0 and L3:a3 x+b3 y+c3=0 are always concurrent given that
∣∣ ∣∣a1b1c1a2b2c2a3b3c3∣∣ ∣∣=0
Let L1 be a straight line passing through the origin and L2 be the straight line x + y = 1. If the intercepts made by
the circle x2+y2−x+3y=0 on L1 and L2 are equal, then which of the following equations can represent L1
