Answer:
option A is correct.(Every plane must have three intercepts.)
Step-by-step explanation:
" Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension "
The intercept form of the equation of plane in 3-D is given by:

Where l,m,n are intercepts of x,y,z axes and a plane respectively.
Hence, we require all the three intercepts of a every plane.
Hence, option A is correct.

Step-by-step explanation:
Answer: k = -1/3
Step-by-Step Explanation:
=> 3x - 2ky + 4 = 0
Value of ‘x’ = -2
Value of ‘y’ = 3
Substitute values of ‘x’ and ‘y’ :-
=> 3x - 2ky + 4 = 0
= 3(-2) - 2k(3) + 4 = 0
= -6 - 6k + 4 = 0
= -6k = 6 - 4
= -6k = 2
= k = 2/-6
=> k = -2/6 = -1/3
Therefore, k = -1/3
