Question

Decide whether the pair of lines is parallel, perpendicular, or neither.

Answer 1

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 2

Answer:

perpendicular

Step-by-step explanation:

perpendicular because m1×m2=-1
