There are many a ways of getting an equation from a given graph. There could be many a ways of doing the work vice-versa. However, it is important to get a proper method or procedure of getting the same. Ones you get to know the method it becomes very easy to get and equation out of any graph. We in this article tend to emphasize on one such method. If you follow the steps one by one, you will understand clearly and it will no more be a problem for you to get an equation out of a graph.

Take a line of a value such as y = 3, now every gap on the particular graph is equal to 3 units over the axis of x. the entire horizontal row will have the equation as the similar format. For example y = – 6.5. This is so because all of them are written in the similar manner. This is how it follows, see, k will be representing the exact numeration on the graph. Now taking the similar option it will be represented vertically onwards. I.e. k = x.

The equation that can be termed as a linear equation for example x= .004y + 23 will as well carry a representation as a linear equation. Say you might write it as x = my + b. There are a number of things to be remembered while you get to the equation, this is termed as interception of the slope. So make sure you study the graph before you get to the exact equation.
