Linear equation Is the equation for which each term has only a constant value. Is a product multiplied by one power. The degrees are 0 or 1. These equations are called “linear”. The general form of linear equations in variables x and y is {\displaystyle y=mx+b\!}. line on a graph . For example the graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. So +1 is also needed. And so: y = 2x + 1 I thing this subject is very good and very understand I like it and it very easy for me. And it can help me in the university and the Future.
