96. | a Ϫ b | ϭ | b Ϫ a | 97. | a Ϫ b | Յ | b | ϩ | a | 98. 1, we saw how a one-to-one correspondence between the set of real numbers and the points on a straight line leads to a coordinate system on a line (a onedimensional space). A similar representation for points in a plane (a two-dimensional space) is realized through the Cartesian coordinate system, which is constructed as follows: Take two perpendicular lines, one of which is normally chosen to be horizontal. These lines intersect at a point O, called the origin (Figure 7).

Next, recall that if p /q (p, q, positive integers with q 0) is a rational number in lowest terms, then the expression b p/q is defined as the number (b1/q) p or, equivalently, q 2b p, whenever it exists. 8283 Expressions involving negative rational exponents are taken care of by the definition b Ϫp/q ϭ 1 b p/q Thus, 4Ϫ5/2 ϭ 1 1 1 1 ϭ 1/2 5 ϭ 5 ϭ 5/2 2 32 4 14 2 The rules defining the exponential expression an, where a Ͼ 0 for all rational values of n, are given in Table 3. The first three definitions in Table 3 are also valid for negative values of a.
