The graph of y 2x1 is a straight line. A linear equation is an equation that represents a line on the quadratic system. This type of equation has only one solution and represents a parallel line with the y-axis.
1 Linear Equation Formula.
When x increases y increases twice as fast so we need 2x. Linear Equations Represent Lines. Simultaneous Linear Equations Two linear equations in two variables which are satisfied by the same pair of values of the variables are called simultaneous linear equations in two variables. Each Formula is explained in brief below.
