We start by understanding what a linear polynomial is and how to find its zero — the value of the variable that makes the expression equal to zero. Then, we move to the visual side: plotting the graph of a linear polynomial on the coordinate plane. Through a clear example, you'll learn how to identify the zero directly from the graph by locating the point where the line crosses the x-axis.
