Question

# In a three-dimensional space, the equation $$3x - 4y = 0$$ represents.

A
A plane containing Zaxis
B
A plane containing Xaxis
C
A plane containing Yaxis
D
Passing through (0,0)

Solution

## The correct option is A A plane containing $$Z-axis$$If we consider the z-part also, then the equation is $$3x-4y+0z=0$$Which means on putting any value of z equation will have no effect as $$0\times z=0$$$$\therefore$$ it will be a plane containing $$Z-axis$$.($$\because$$ it will pass through all points z if it satisfy condition for$$(x,y)$$)(D) is not right because its plane and not a line so it will pass through $$(0,0,0)$$ not $$(0,0)$$.Hence, $$(A)$$Maths
