Step-by-step explanation:
Standard equation of line is : y = mx + c, Where m represents the slope
Given Equations :
Two lines are parallel if the slope of the lines are same.
Two line are perpendicular if the product of the slope = - 1
Clearly slopes are not equal , therefore the lines are not parallel.
product of the slope is - 1, therefore the lines are perpendicular.
