Algebra-1

The figure described consists of:

One ascending line (positive slope).

One descending line (negative slope).

The lines intersect at a right angle (90 degrees).

Description of Key Terms:

A. Perpendicular Lines: Lines that intersect at a right angle (90 degrees). This accurately describes the lines in the figure.

B. Parallel Lines: Lines that run in the same direction and never intersect. Since the lines in the figure do intersect at a right angle, they are not parallel.
