Respuesta :
9x = 3y - 54
3y = 9x + 54
y = 3x + 18
Parallel = same slope
The slope is 3
3y = 9x + 54

The slope is 3
Answer:
21
Step-by-step explanation:
subtract 9 on both sides to make your x axis by itself
y=mx+b
since -3y and -63 will cancel out each other and make a positive when you divide
-3y /63
y=21
also your when the x is alone it is always 1
