y=4x-1
when u substitute and see,
(0,-1)(-2,-9),(1,3) satisfy this eqn.since we have only this eqn and no more info,clearly we can say tht these points satisfy and are the answers..
there is no wrong if a question has 3 answers..

y = 4x -1
Answers:
b) For x = 0; y = -1 => (0, -1)
c) For x = -2; y = -9 => (-2, -9)
d) For x = 1; y = 3 => (1, 3)

Just plug in the values and you'll see.
(0,-1), (-2,-9) and (1,3) all work.

Because all of the points given ((2,5) etc) are points that lie on the line described by y=4x-1

In this case you have one equation with two unknowns. In any case where the unknowns outnumber the equations, you are allowed to take one of the unknowns as arbitrary.
Basically, you can make up a value for x or you can make up a value for y, but not both.
