Answer 1

Parallel: slope is 1

Perpendicular: slope is -1

Explanation:

y = x -1

For a parallel line, the slope would be equal to the slope in this equation. The slope is the number (coefficient) before the letter x. In this case, we do not see a number before the x, so we assume that it is one.

For a perpendicular slope is the opposite inverse of the slope of this lien. Since the slope of this line is 1. One as a fraction is 1/1 If I flip this upside down, it is still 1/1 which is one. Since this slope is positive, its opposite would be negative. The perpendicular slope would be -1
