Answer:
A. y = 6
Explanation:
Y= 0 is equation of x - axis
equation of any straight line which is parallel to x-axis and at distance of a from it is given y = c.
Therefore, from the given option only option A y =6 is in form of y = a and hence is the correct answer.
_______________________________________
Also we know that for two lines to be parallel , their slope should be equal.
slope of line y = mx + c is m
slope of y = 0 here m = 0, hence slope is 0
out of the given option
only for y - 6 slope is 0 and hence it is the correct answer.
