Whatever notation you use
when you post a math question, you should take the time to be neat, organized,
and clear when you post your questions. Define your terms and variables;
don't expect the tutors to read your mind to divine your meaning. Include
the actual question and its instructions; you'd be surprised how often
this information is left out. Write an intelligent subject line,
but include everything within the post; don't put crucial information
only in the subject line. Show all the steps you've tried, even if you
think they're wrong; and state clearly what is the difficulty you're having.
3) Find the x- and y-intercepts of the graph of 3x + 4 = y algebraically.
I can find intercepts from the graph (as long as they're whole numbers), but I'm having trouble with the "algebraically" part. How am I supposed to do it "algebraically"? If you could show me a similar example, so I can work this one on my own, that would be great.
Thank you for your help.

how do u do
3x+4=y

ASAP!!!!!
Subject: graphing 3x + 4 = y
Here is the question I'm working on:
5) Graph the equation 3x + 4 = y
I know how to draw the points and then the line once I have some points, but I'm not sure what points I'm supposed to pick. Is there any secret, or is it up to me? Can I pick whatever I want, or are there certain x-values I should use?
Thank you for your time.

Subject: finding slope and intercept of 3x + 4 = y
Here is the question I'm working on:
7) State the slope and y-intercept of the graph of 3x + 4 = y
I know in the slope-intercept formula, "y = mx + b", that m is the slope and b is where the y-intercept is. So am I right that they just want me to read off "m = 3" and "b = 4" from the equation? That seems too easy. Am I I missing something? (I've been out of school for twenty years, so I'm not feeling very confident.)
Thank you for your comments and corrections!
The three "poor"
posts are word-for-word the same, but you can tell from the "good"
posts that they aren't actually the same question.
The problem, of course,
is that "HELP!! how do u do it?" doesn't actually say
anything. The left-hand column's posts would be very frustrating for a
tutor to try to deal with, and are much less likely to receive a helpful
reply.
Instead, take your
cue from the right-hand column's "good" posts:
Take the time to spell
words correctly: use "algebra" and "solve" instead
of "algerba" and "slove".
Write words out completely:
use "you" instead of "u", "know" instead
of "noe".
Capitalize properly:
use "I" instead of "i", and use capitals for names
and at the beginnings of sentences.
Punctuate sensibly:
using periods at the ends of sentences is helpful; using twenty exclamation
marks is not.
Space your math generously
(using fixed-width fonts, if possible) and use all-black type: The statement
"3x^2
+ 4 = y" is
much easier on the eye than is "3x^2+4=y",
especially for those of us old-timers who have to squint at your
posts through bifocals.
You're asking somebody
for help, so ask clearly: Don't post cryptic text-message-lingo
stream-of-consciousness math, as it is highly unlikely that the tutors
will be able to figure out what the heck you meant.
Be friendly: Avoid posting
things like "math sux" or "i hate math" or other
expressions of hostility.
And be considerate: Tutors
at free services are volunteers, people who work, eat, and sleep in
addition to helping students; they aren't sitting at their computers with
bated breath, just waiting for your question to come in, and they're
not getting paid, so ask nicely and be prepared to wait as much
as a couple of days for a reply.
And always, always, always
remember to say "please" and "thank you".
