we have

[tex]4x-y=1[/tex]

This is the equation of the line in standard form

so

The graph is a straight line

we are going to proceed to verify the first two cases only

case A) It is a straight line joining the points [tex](0, -1)[/tex], [tex](1, 3)[/tex], and [tex](-1, -5)[/tex]

Using a graphing tool

The three points are on the straight line

see the attached figure N [tex]1[/tex]

case B) It is a straight line joining the points [tex](4,-3)[/tex], [tex](-1, 2)[/tex], and [tex](-4, 5)[/tex]

Using a graphing tool

The three points are not in the straight line

see the attached figure N [tex]2[/tex]

therefore

the answer is

It is a straight line joining the points [tex](0, -1)[/tex], [tex](1, 3)[/tex], and [tex](-1, -5)[/tex]
