The info is all there! Determine the slopes and you will know!
Recall that in the form y = mx + b, that m is the slope. You have that already with your two equations --- the first is m=1 and the second is m=-1
Parallel lines have the same slope
Perpendicular lines have slopes that, when multiplied together, yield -1
you have m=1 * m=-1 .... 1 * -1 = -1
therefore your lines are perpendicular
Do you understand this? Do you think you can do one of these problems on your own or on a test?
Good luck...

They're perpendicular.
there's an imaginary 1 in front of X, so the first slope is 1, the second slope is -1, so the slopes are opposites, which makes them perpendicular.
