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).
I believe it is A.
First; graph the equation. You'll need to rewrite it so it is in slope-intercept form (y=mx+b), which would get you y=4x-1. After you graph it, look for the points you stated inside the line.
Plug in those values and it should = 1
I wrote it in a graph and the y-intercept was -1(duh), and the x-intercept was 0.25.

Alright; you have one point that you know for certain is on the line which is 0, -1. However; finding the other points is a drag. So; input the values that the answers give you and solve. If each ordered pair works in the graph; that's the answer. If NONE of the points work; this problem is written wrong.
Scratch off graph for equation. Sorry!
Just enter the given order pairs they gave you,
You don't need the graph.
Ah, okay. Thanks to both. Winter break did no good to meh.
Tomorrow's midterms. I know the struggle.
