Which statements about the system are true? Select two options
Y=1/3x-4 3y-x=-7
The system has one solution
The system consists of parallel lines
Bothsire tave the same slope,
Both ties have the same y-Intercept
The equations represent the same line

Answer 1

Answer: The system consists of parallel lines

Explanation:

Given system of lines :

`y=\frac13x-4`

`3y-x=-7`

Substitute
`y=\frac13x-4` in
`3y-x=-7`, we get

`3(\frac13x-4)-x=-7\\\\\Rightarrow\ x-12-x=-7\\\\\Rightarrow\ -12=-7` , which is not true.

That means , system has no solution.

i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]
