. F.3). If the first line intersects the x-axis at the point ... then we associate the ordered pair of real numbers (a, b) with the point P. The number a is called the x-coordinate or abscissa of P and the number b is called the y-coordinate or .... As illustrated in Figure F.12, intersections of a graph with the x-axis have the form (a, 0).
