 * A** **linear equation is an equation in which each term is either a constant or the product of a constant times the first power of a variable. Such an equation is equivalent to equating a first degree polynomial to zero. These equations are called "linear" because they represent strait lines in Cartesian coordinates. A common form of a linear equation in the two variables //x// and //y// is y=mx+b.**

Desirée Mack To graph linear equations you need the slope and y-intercept.
 * First**, find the y-intercept on the graph and plot the point.
 * Second**, from that point, use the slope to find another point and plot it.
 * Third**, draw a line that connects the two points.

To get a liner equation you need a slope and a Y-intercept like in every graph so you need to subtract the X from X and the Y from Y it is a straight line that hits all the plot points on the spot and when you plot the formula there should be a liner equation

__Amber Housley A linear equation is an algebraic equation in which each term is a constant. These equations are called linear because they represent straight lines.

Mary Altamuro A mathematical expression that has an equal sign.

Brandon Williams__ [|View the changes] A linear equation is an algebraic equation in which each term is either a constant or the product of a constant times the first power of a variable. As you can see in the picture this what a linear equation looks like.    **Dylan Arroyo** __Example of how to solve an linear equation: Y=mx+b M is the slope X is X B is the y intercept First find the slope of the line. You can find the slope by using the slope formula which is Y2-Y1÷X2-X1

In this case it would be 4-2 ÷ 3-1= 2÷2= 1. The slope of the line would be 1.

The Y intercept would be 0,1.

So the linear equation is Y=X+1. Also to check if this is correct you can actually make a graph and use the equation and plot in one of numbers in the equation too see if the plots match the line. (Oswald Dembowski)

I found this site that has a caculator in it for liner equations http://www.analyzemath.com/solvers_calculators/linear_equation_solver.html ( information given by Andrew Smtih)__

__**Linear Equations**__

When finding the equation of the line there are to important things you need to know. You need to know the slope and the Y-intercept of the line that you're trying to find the equation of. In order to find the Y-intercept you need to know the slope of the line. There are two way to find the slope of the line. You can pick to points on the line that form a right angle and count the number of blocks it rises and the number of blocks it runs or you can use the formula, which is **__y1 - y2__ .** When you find the slope, in order to find the Y- intercept you must plug in the slope and one of the coordinates into this formula y=mx+b or you could see where on the graph does the line cross the y axis. The m represents the slope and the b represents the Y-intercept, just plug in a coordinate to find the Y-intercept.
