WebGraphically this equation can be represented by substituting the variables to zero. The value of x when y=0 is 5x + 3 (0) = 30 ⇒ x = 6 and the value of y when x = 0 is, 5 (0) + 3y = 30 ⇒ y = 10 It is now understood that to solve linear equation in two variables, the two equations have to be known and then the substitution method can be followed. 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.
