The equation l1: x=7 represents a vertical line since the value of x is always 7, and the value of y can vary.
The equation l2: y=7/9 represents a horizontal line since the value of y is always 7/9, and the value of x can vary.
Since the lines are vertical and horizontal, they are perpendicular to each other.
Determine if the equations represent parallel lines, perpendicular lines, or neither.
l1: x=7
l2: y=7/9
