Determine if the equations represent parallel lines, perpendicular lines, or neither.

l1:y=6/5
l2:x=4

1 answer

The equation l1: y = 6/5 represents a horizontal line because the y-value is constant at 6/5 while the x-value can be any number.

The equation l2: x = 4 represents a vertical line because the x-value is constant at 4 while the y-value can be any number.

Since a horizontal line and a vertical line are always perpendicular, we can conclude that the equations represent perpendicular lines.
