Answer:
No parallel lines
Lines 1 and 3 are perpendicular
Step-by-step explanation:
Given:
Required
Determine if they are parallel, perpendicular or not
The slope intercept of a line has the form:
Where
First, we calculate the slope of each lines
Compare the above to
Make -6y the subject
Divide through by -6
Compare the above to
Divide through by 3
Compare the above to
So, we have:
None of the slopes are the same, so none of the lines are parallel.
However, lines 1 and 3 are perpendicular.
This is shown below
When the slope of two lines satisfy the following condition, then they are perpendicular.
This gives:
