Answer: Perpendicular

Explanation:

Given are two equations as

We have to find whether these two are parallel or perpendicular or neither

For this first we have to find the slope of these two lines

I line slope = 1

II line slope =-1

Since slopes are not equal, the lines are not parallel.

Let us check product of these slopes. IF product =-1 the lines are perpendicular

We find that product =

Hence two lines are perpendicular
