WILL MEDAL Which of the following statements best describes the graph of 4x − y = 1? It is a straight line joining the points (0, −1), (1, 3), and (−1, −5). It is a straight line joining the points (4, −3), (−1, 2), and (−4, 5). It is a curve joining the points (4, −1), (2, 3), and (4, 1). It is a curve joining the points (0, −1), (−1, −3), and (1, 5).

Verified Answer :

we have

\(4x-y=1\)

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 \((0, -1)\), \((1, 3)\), and \((-1, -5)\)

Using a graphing tool

The three points are on the straight line

see the attached figure N \(1\)  

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

Using a graphing tool

The three points are not in the straight line

see the attached figure N \(2\)    

therefore

the answer is

It is a straight line joining the points \((0, -1)\), \((1, 3)\), and \((-1, -5)\)
