horizontal line will be parallel to x axis and vertical line will be parallel to y axis


the slope of  x axis is 0

so parallel lines will have same slope thus horizontal line has slope =0

x=2 is parallel to x axis with slope = 0


so answer is d  ,  x= 2


hope you understood...please message if you have any doubts ...thank you
