Linear+Equations

====In this wiki page you will learn how to use Linear equations, tables and graphs. We will view how they all connect and how to change one to the other. (equation to table to graph and so on)This page also includes links to other websites, explanations and examples. (google and youtube.com)==== = = =LINEAR : EQUATIONS TABLES AND GRAPHS=

A graph to a table and to an equation is a very simple process! Here is a short video by a teacher to show you the connection between equations, tables and graphs! media type="youtube" key="m_mRQT7pUUw" height="385" width="480" And here is a personal video, very simple, of equations, tables and graphs! ENJOY! media type="youtube" key="OcZoRDs2McI" height="385" width="640"

1) you have a graph with a minimum of two points This graph shows the first point at (0,-1) and the second is at (3,2)

2) Make the equation! This is very easy. First we need to use the format for linear equations.... : M stands for slope and B stands for the y intercept. Here is an example on a different graph. Better? Now if we look at the graph that we are working on, we can see that the y intercept is -1. BECAUSE the line crosses the y axis at negative one! So one way to write it is (0,-1) from x to y. SO the y intercept is -1! Because the line crosses the y axis at negative one. one way to write it is (0,-1) or x:0 y:-1:)

Now we move onto slope. there is a separate page for learning the slope of a line. SO PLEASE GO TO SLOPE IN THE NUMBER SENSE SECTION TO LEARN EASY AND BETTER ABOUT SLOPE!!!

TO conclude the equation: it would look like this: And lastly for the table!!! this is the fastest and easiest to do. first make a table with X and Y. don't forget to label numbers 0 and onwards. the reason that the x axis goes up by 3 is because the first point is on x=o and the second on x=3 so there is no point on one. This is valuable to remember! one always has to check by how much the x is increasing by!!! now you can look at the graph at the first two points. since we know that when x is zero and y is?, ? being the y intercept, you can fill out the first plot at zero. TO find the rest of the point one must simply see the slope pattern. 3/3 and increase 3 by the table. Here:

NOW YOU HAVE LEARNED EVERY THING ABOUT LINEAR TABLES GRAPHS AND EQUATIONS!!! CONGRATS!!!!
