A linear equation is an equation for a straight line. These are all linear equations: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: 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.
