A. (2, 0) B. (0, 2) C. (-2, -2) D. (2, 2) 相关知识点: 试题来源: 解析 A。解析:在平面直角坐标系中,点在 x 轴上时,其纵坐标为 0。点(2, 0)的纵坐标为 0,所以在 x 轴上。选项 B 点(0, 2)在 y 轴上;选项 C 点(-2, -2)不在坐标轴上;选项 D 点(2, 2)不在坐...
Which of the following points lies on the x-axis? A. (0, 5) B. (5, 0) C. (0, -5) D. (-5, 0) 相关知识点: 试题来源: 解析 B。在平面直角坐标系中,位于 x 轴上的点纵坐标为 0。选项 B 中坐标为(5, 0),纵坐标为 0,所以该点在 x 轴上。

B) 1 C) -1 D) Any number Solution The answer is A. The ordinate of all points on the x-axis is zero because ordinate ( or y-coordinate) of a point is the perpendicular distance of this point from the x-axis measured along the y-axis. If the point lies...
<p>To determine which points lie on the x-axis, we need to understand the condition for a point to be on the x-axis in the coordinate plane. A point is represented as (x, y), where 'x' is the x-coordinate and 'y' is the y-coordinate. For a point to lie o
