Yes a repeating decimal can be written as an integer
C) they are parallel
as the slopes must be equal due to the fact they are both perpendicular to line n ( for a perpendicular line you flip the slope and change the sign , so both of them being perpendicular to n the slopes must be equal)
They cant interest at all since they are perpendicular and they may not be the same line
You need to do the distributive property first so the answer is C
You put it into a graphing calculator and it'll come up with answer D.
