Check out Bas Rutten's Liver Shot on MMA Surge: http://bit.ly/MMASurgeEp1 In this video, Mahalo math expert Allison Moffett gives you an introduction to linear equations. What is a Linear Equation? --------------------------------------------------------------------- A linear equation is a mathematical expression with an equal sign and two variables that can be represented by a line on a graph. An example of such an equation would be y=3x-4. With these equations, both variables can change the number that they represent, but as one changes, the other must change according to the formula. In this case, x is the independent variable and y is the dependent variable. Identifying Linear Equations --------------------------------------------------------------------- In the example of?y=3x-4, you know it is a linear equation because all the variables are only raised to the power of one. It isn't written out that way, but it's understood. If there were an x squared or x cubed, it wouldn't be a linear equation. Graphing Linear Equations --------------------------------------------------------------------- When you represent linear equations on a graph, the result will be a straight line that slants (or slopes) to either the right or left and intersects both axes at different points.
