For this case we have to by definition:
If two lines are parallel then their slopes are equal.
If two lines are perpendicular then the product of their slopes is equal to -1.
We have the following equations:
We manipulate the equation to convert it into the slope-intersection form 
Where:
m: It's the slope
y: It is the cut-off point with the y axis.
So:
From the second equation given we have:
We manipulate:
It is observed that the slopes are equal, so the lines are parallel,
ANswer:
The lines are parallel.

Answer:
Step-by-step explanation:
Step-by-step explanation:
g/6 - -53 = 57
g/6 + 53 = 57
g/6 = 4
g = 4×6 = 24

Answer:
- Joe: 57
- Scott: 19
- Laura: 28
Step-by-step explanation:
Let s represent the number of orders Scott served. Then we have Joe served 3s, and Laura served (s+9). The total of orders served is ...
3s +s +(s +9) = 104
5s = 95 . . . . . . . . . . . subtract 9 and collect terms
s = 19 . . . . . . . . . divide by 5
3s = 3×19 = 57
s+9 = 19+9 = 28
Joe served 57 orders, Scott served 19, and Laura served 28 orders.
