Question

74. The equation of the line parallel to X-axis and passing through the origin is
(A) x/1 = y/0 = z/0
(B) x = y = z
(C) x/1 = y/2 = z/0
(D) none of these

Answer 1

Answer:

Option(A)

Explanation:

We have given that the equation is parallel to x-axis means that every equation is in the form:-

$y=n\;and\;z=m$, where m and n are integer.

We have also given that the same line passes through origin, it means that the value of m and n is zero.

So, we have the equations of the form:

$y=0;\\z=0$

So the exact solution is:

$\dfrac{x}{1}=\dfrac{y}{0}=\dfrac{z}{0}$
