Answer: The correct option is, It is a line joining the points whose x and y coordinates add up to 4.

Explanation:

The given equation is,
x+y=4

when we take x = 1 then


1+y=4


y=3

when we take x = 2 then


2+y=4


y=2

From this we conclude that the sum of 'x' and 'y' coordinates is always equal to 4.

Hence, the correct answer is, It is a line joining the points whose x and y coordinates add up to 4.
