Answer:
B.
Step-by-step explanation:
Perpendicular lines always intercept at a right angle (90 degrees).
b. lines that meet at a 90 angle
Perpendicular lines are lines that intersect at a right (90 degrees) angle.
So, the correct answer is b. lines that meet at a 90 angle.
If you want to know if two equations are perpendicular, take their slopes. The slopes of perpendicular lines are opposite reciprocals of each other.
