Answer:
Correct: Option a. negative reciprocals
Step-by-step explanation:
Perpendicular lines are defined as those who intersect at an angle of 90°.
There is an easy way to find out if two equations of lines correspond to perpendicular lines or not.
If line 1 is
y=m1x+b1
And line 2 is:
y=m2x+b2
The condition for the lines to be perpendicular is that:
m1*m2=-1
Solving for m2:
[tex]\displaystyle m2 = -\frac{1}{m1}[/tex]
As seen, both slopes are negative reciprocals.
Correct: Option a. negative reciprocals
