例1如图1,在平面直角坐标系中,已知点A(2,3)、B(6,3),连接AB.若对于平面内一点P,线段AB上都存在点Q,使得PQ≤1,则称点P是线段AB的“邻近点”.(1)判断点D(7/5,19/5)是否是线段AB的“邻近点”(填“是”或“否”);
Example 1 As shown in Fig. 1, in plane rectangular coordinate system, known points A (2,3) and B (6,3) are connected to AB.If there is a point Q on line AB for a point P in the plane, PQ ≤1, then point P is the “neighbor point” of segment AB. (1) Judge whether D (7 / 5,19 / 5) is the “neighbor point” of segment AB “Or ” No ");
