OMG

OpenStudy (misssmartiez):

-_- He deleted my post when I was going to POST a question.

OpenStudy (anonymous):

ur gonna get it

OpenStudy (misssmartiez):

It was an attachment. Thanks.

OpenStudy (misssmartiez):

I was posting when HE just closed my chat. It wasn't 'spam'.

OpenStudy (misssmartiez):

Anyway.

OpenStudy (misssmartiez):

touchie.

OpenStudy (misssmartiez):

OpenStudy (misssmartiez):

^ I was going to post this underneath the chat. Anyone know this? I am stuck on this. Though.

OpenStudy (misssmartiez):

First I thought x = _ + 2 but then it seemed something else.

OpenStudy (anonymous):

y = 3x - 2

OpenStudy (misssmartiez):

Are you doing what Y is or X?

OpenStudy (anonymous):

@MissSmartiez What y is. To get x: solve for x: x = (y -2)/3

OpenStudy (misssmartiez):

Ok,

OpenStudy (mathmale):

Look for a rule that connects each x with the corresponding y. Use any two points to determine the equation of the line connecting those 2 points. Write the equation of this line. Then, check it to ensure it actually works. Then, use this equation to find the unknowns. I suspect the relationship is linear. It's up to you to check that out.

OpenStudy (anonymous):

(y+2)/3 my bad

OpenStudy (misssmartiez):

Linear? Well, I haven't learned that yet. It is mostly about the sequence or the function rule mathmale?

OpenStudy (misssmartiez):

So, what do I do? To find j?

OpenStudy (mathmale):

Function. I'd bet you have learned a bit about linear functions already, even if that name didn't come up. I explained it, step by step. Hope you'll try going through those suggestions.

OpenStudy (mathmale):

You can guess, of course, but this method is grossly inferior to a careful mathematical approach.

OpenStudy (misssmartiez):

Ok

OpenStudy (mathmale):

Have you found the slope of a straight line thru 2 given points before?

OpenStudy (misssmartiez):

No

OpenStudy (mathmale):

Have you seen the equation y=mx+b before?

OpenStudy (misssmartiez):

No. I am only in 7th grade, I am new to functions. (I feel incompetent)

OpenStudy (misssmartiez):

Maths not my thing <3

OpenStudy (misssmartiez):

Is it +2 then +3?

OpenStudy (mathmale):

Think: "math could be my thing if I study it diligently and practice a lot."

OpenStudy (mathmale):

Could you graph (5,13)? x-coordinate is 5 and y-coordinate is 13.

OpenStudy (mathmale):

If so, leave enough room on your graph so that you could graph (12,34).

OpenStudy (misssmartiez):

My brain isn't wired around math's complicated procedures. More of science, English, and history. Basically anything but science but I must know this to ace chemistry and such... Math is the base of science... However, which graph do you mean?
