Will give metal :) Please help!

Which of the following statements best describes the graph of -5x + 2y = 1?

It is a curve joining the points (-5, 2), (2, 3), and (4, 1).

It is a curve joining the points (-1, -3), (-1, -3), and (1, 5).

It is a straight line joining the points (1, 3), (3, 8), and (-3, -7).

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

Answer 1

What type of equation is -5x + 2y = 1?

Answer 2

A linear.

Answer 3

I believe

Answer 4

Since it is a linear equation, will the graph be a line or a curve?

Answer 5

A line.

Answer 6

That eliminates A and B. Now, in order to determine which choice is correct, all you need to do is plug in at least one of the points given. Since the coordinate pairs should satisfy the equation, if you plug in the points, you can see which choice is correct.

Answer 7

Hmm.. I want to say D but I'm thinking C is correct..?

Answer 8

Wait, I think D.

Answer 9

Plug in a point given in D and see if it satisfies the equation. If it does, then it is correct. Otherwise, it's C.

Answer 10

Never mind, I say C because the 1 is not negative.

Answer 11

Okay, thank you.
