Hi, there--

THE PROBLEM:
How do you write a linear equation?


A SOLUTION:
There are many different linear equations, but they all have this kind of form:

Ax + By = C

A, B, and C are numbers. 

A and B can be any number, but they can't both be zero in the same equation.
C can be any number.

Here are some examples:

3x + 2y = 10

4x - 6y = -1

If A is 0, then there is no x in the equation. This is the equation for a horizontal line.
Some examples would be

2y = 5 
y = -300

If B is 0, the there is no y in the equation. This is the equation for a vertical line.
Some examples,

x = 3
-7x = 2/3

There is a lot more to linear equations, but this will get you started. If you have a specific 
problem you are trying to figure out, feel free to email me.

Hope this helps!
