Graphics, Figures & Tables ⇒ A bunch of newb questions :)

[LaTexLearner]

I've put my newb questions in the code, using the % symbol. If it's too many for one thread, let me know. I *think* they're mostly small questions, though.

Code: Select all

\documentclass[12pt,letterpaper]{article}

\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\usepackage{array}
\usepackage{booktabs}
%Is there an easier way to make horizontal lines in tables than using the booktabs package?

\begin{document}

\maketitle

%All 3 of the vspaces below are 5pt. Why isn't the vertical spacing consistent?

\noindent \textbf{The System}

\vspace{5pt}

\noindent Equation 1: $5x+3y=9$\\

\vspace{5pt}

\noindent Equation 2: $-4y+10=x+15$

\vspace{5pt}

%Why don't the borders of the tables touch? And why does it give me errors when I try to put "\midrule" anywhere else, e.g. line 42 or 44?

\begin{tabular}{|p{5cm}|p{2.5cm}|p{2.5cm}|p{2.5cm}|}
\midrule
Possible Solution&\raggedright Solution to Equation 1?&\raggedright Solution to Equation 2?& \raggedright Solution to The System? \\
%Why the heck are all these equations in the column farthest to the right? How do I put them in the left-most column?
$x=2, y=5$\\

$$x=1, y=2$$\\

$$x=3, y=-2$$\\

$$(-2,3)$$\\

$$(-5,0)$$\\

\end{tabular} 

\begin{enumerate}
\item What is the solution to the system?
\item How can you tell if you have a solution to a system?
\item The system of equations above has \_\_\_\_  equations. A solution has to satisfy \_\_\_\_ of them. 
\item If a system of equations has 25 equations, then a solution must satisfy \_\_\_\_ of them.
\item If a system of equations has $n$ equations, its solution must satisfy \_\_\_\_ of them. 
\end{enumerate}

%How do I make the blank spaces for writing a continuous line instead of four small separated underscores?

\noindent \textbf{Another System of Equations}
%Again, what's with the inconsistent spacing here?
\vspace{5pt}

\noindent Equation 1: $x-2y=-11$\\

\vspace{5pt}

\noindent Equation 2: $3x=2y-13$\\

\vspace{5pt}

\noindent Decide if the following are solutions to the system above or not.

\begin{itemize}
\item $x=-3, y=4$
\item $(-1,5)$
\item %Easiest way to draw an x-y plane graph from (-5,-5) to (5,5) with a dot on (1,4)?

If it's too many for one thread, let me know.

Gladly - yes, too many per thread. It should be one question per topic, no matter how small. We got space for millions of topics, and tags to sort them. And the title should speak for the content.

Or with more words.

Just for fun, imagine, that you would maintain a public discussion forum about LaTeX, which shall be a useful knowhow Internet archive with LaTeX solutions. And people should find topics, if they google for some meaningful keywords.

We answer questions for more than just a single question poster to throw away afterwards.

Now, how should this topic title be sorted? How to be understood by searching users? Why mixing questions?

If you would use questions to get answers for a good solution archive, you may

• choose a title which describes the question or error,
• post one topic for each question.

What do you think? Can we improve? Would be more motivating to work on answers.

@ Stefan: I didn't quite understand all your post, but I will split up mine into smaller chunks sometime tomorrow.
