Answer:
The answer to the equation should be C
Answer:y=x/3
Step-by-step explanation:
x-3y=0
or,x=3y
y=x/3
Step-by-step explanation:

-14x²-1≠0
x²≠ -1/14
Option C
Answer: y= 1
This because the line has no slope so the equation really looks like this if we were to follow the y=mx+b format.
y=mx+b
y= 0x + b
because the number "0" multiplied by any value is still zero we can exlude that from the final equation of the line. In this case since m=0, the line is y=b.
b is the y intercept, or the value of y when x = 0.
So, because y=1 when x is 0, "b"= 1
y=b
y=1
