Decide whether the pair of lines is parallel, perpendicular, or neither.
2 answers:
Answer:
perpendicular
Step-by-step explanation:
Let's find the slope of both lines
For line 3x-6y=-1
-6y=-1-3x
y=1/6+½x
m=½
For line 18x+9y=-14
9y=-14-18x
y=-14/9-2x
m=-2
m1•m2=½×-2=-1
since m1•m2=-1 the lines are perpendicular
Answer:
perpendicular
Step-by-step explanation:
perpendicular because m1×m2=-1
