You can tell that a line is parallel if the lines can go on forever without crossing or intersecting. A line is perpendicular when the lines intersect at a right angle. If the slopes are either equal or negative reciprocals, they cannot be parallel or perpendicular.

Answer:
-3
Step-by-step explanation:
Isolate -3y by subtracting x from both sides
-3y = -18 - x
Divide everything by -3
y = 6 + 1/3x
Slope is 1/3, and perpendicular lines have the reverse reciprocal slope, so our slope is -3
Answer:
n is less than or equal to 83
Step-by-step explanation:
-65=6b-11
Add 11 to both sides to get rid of the -11 on the right side
-54=6b
Then divide both sides by six to find the value of b
-9=b
So b is -9
