In order to find if two lines are parallel or perpendicular or neither, following rules are used:
- If the slope of two lines is the same, the two lines will be parallel
- If the product of slopes of two lines is -1, the two lines will be perpendicular to each other.
- If none of the above two conditions is being satisfied, this mean lines are neither parallel nor perpendicular.
So the steps that must be followed are:
- Find the slope of the given lines.
- Use the values of the slope to check which of the above point is being satisfied and draw the conclusion accordingly.
