note that y decreases by 1 when x increases by 2. So, start with

y = -1/2 x

But, -1/2 (2) = -1, and y(2) = 1. So,

y = -1/2 x + 2
I just want to let all of you here know that teachers can see the answers here, too and will know that you are cheating.
If you've posted your answers here, please be advised that you are enabling students to cheat on their tests. This is a test question.
Where is this a test from? just wondering so I can check.
Hello, I am a math teacher from the school where the test question is from ( Connections Academy) We can clearly tell when a student's work is not his or her own. Five of my students have already had Honor Code violations due to copying from this website.
Which teacher are you then? Huh? Whoa re your students?
