Question

Which set of points are on the line y = 2x-1

Answer 1

do you have some options?

Answer 2

okay, all you have to do is substitte the x value of each point (x,y) and see if you get the corresponding y value, for example the first given point (0,-1)
y=2(x)-1
y=2(0)-1
y=0-1
y=-1
the point (0,-1) lies on this line
try the other points

Answer 3

if you do the subtitution process you will find the right set
