Welcome to OpenStudy! Could you post the graph :3

anonymous · Answer

I know the answer it is Each year, the machinery loses a value of $4, 500 I just need an explanation on why it is 4,500

wat

nottim · Answer

how did you even get my name. i haven't been on for more than 2 sec, for more than 7 months.

nottim · Answer

hey, what graph.

anonymous · Answer

that's not the question

nottim · Answer

the graph isn't part of the question?

anonymous · Answer

let me get the graph

thx mate.

nottim · Answer

now, tell me what formula you are going to use.

nottim · Answer

I mean, what do you, dear fellow, mean by "Which statement most closely matches this relationship?"

nottim · Answer

in science, its important to know the process almost more than the answer. when you, "which statements", it sounds like a multiple choice question. is it?

anonymous · Answer

yes

nottim · Answer

Wait, I think I understand you slightly. You already googled the answer, but wanna know how to get there. Awesome. Alright, important thing first is to determine the formula for this situation.

nottim · Answer

Its a linear line, going down. Which means it has slope.

nottim · Answer

An equation for slope is y=mx+b.

anonymous · Answer

ok and yes I admit I googled the answer

nottim · Answer

Substitute any 2 lines into y=mx+b, where (x,y) is a point on the line. Don't worry lots of children do it. I'm jsut glad you want to figure out the real process like real scientists actually do.

nottim · Answer

Wait what grade level are you.

anonymous · Answer

7

nottim · Answer

Oh god.

nottim · Answer

What am I doing.

nottim · Answer

Uh.

anonymous · Answer

is this Substitute any 2 lines into y=mx+b, where (x,y) is a point on the line. the explanation

nottim · Answer

Wait no you can't use that.

nottim · Answer

That's like grade 9 stuff. Did you guys already study slope of the line?

anonymous · Answer

nop that's why I want an explanation

nottim · Answer

That would be an explanation if you were in a higher grade.

nottim · Answer

Wait how is it 4500.

anonymous · Answer

trust me it is the right answer

anonymous · Answer

I asked  my teacher if it was the right answer and he said yes

nottim · Answer

Based on both visual perception and visually used data and its calculation, I got a difference answer. Where'd your teacher get his degree?
