Doing so shows that the boundary is not included in the region. When the boundary is included, we use a solid line. The region f(x, y) : y $ 2xg, for example, includes its boundary (see Figure 16). ⁄ E X A M P L E 1 1 Sketch G 5 f(x, y) : jyj . 2 and jxj # 5g. Solution The sets f(x, y) : jyj . 2g and f(x, y) : jxj # 5g are illustrated in Figures 17a and 17b. The set G consists of the points common to these two sets (see Figure 17c). ¥ y y y 10 10 10 ͉ y͉ Ͼ 2 ͉ x͉ Յ 5 x Ϫ10 10 x x Ϫ10 10 Ϫ10 10 ͉ y͉ Ͼ 2 Ϫ10 m Figure 17a f(x, y) : |y| .

The vertical distance of the observation (xi, yi) to L is di 5 jyi 2 ðmðxi 2 x0 Þ 1 y0 Þj 5 jðyi 2 y0 Þ 2 mðxi 2 x0 Þj: We therefore seek the value m for which the sum À Á2 À Á2 S 5 ðy1 2y0 Þ2mðx1 2x0 Þ 1 Á Á Á 1 ðyN 2y0 Þ2mðxN 2x0 Þ is minimized. By expanding each square and collecting like powers of m, we find that S 5 Am2 1 Bm 1 C where A 5 ðx1 2x0 Þ2 1 ðx2 2x0 Þ2 1 Á Á Á 1 ðxN 2x0 Þ2 and À Á B 5 2 2 ðx1 2 x0 Þðy1 2 y0 Þ 1 ðx2 2 x0 Þðy2 2 y0 Þ 1 Á Á Á 1 ðxN 2 x0 ÞðyN 2 y0 Þ : We do not calculate C because its value is not needed.
