A. x-axis B. y-axis C. origin D. quadrant 相关知识点: 试题来源: 解析 A。本题考查横坐标的含义。横坐标表示点在 x 轴上的位置。选项 B y 轴对应的是纵坐标;选项 C 原点不是横坐标表示的位置;选项 D 象限不是横坐标单独决定的。
If the coordinate of a point is (x, y) and it is reflected across the x-axis, the new coordinate is ___. A. (-x, y) B. (x, -y) C. (-x, -y) D. (y, x) 相关知识点: 试题来源: 解析 B。点(x, y)关于 x 轴反射,纵坐标变为相反数,即新坐标为(x, -y)。
A. x-axis B. y-axis C. origin D. quadrant 相关知识点: 试题来源: 解析 B。本题考查纵坐标的含义。纵坐标表示点在 y 轴上的位置。选项 A x 轴对应的是横坐标;选项 C 原点不是纵坐标表示的位置;选项 D 象限不是纵坐标单独决定的。
The coordinate of a point is (-5, 0), then it lies on: A. x-axis B. y-axis C. Quadran
: a coordinate whose value is determined by measuring parallel to an x-axis specifically : abscissa Word History First Known Use 1927, in the meaning defined above Time Traveler The first known use of x-coordinate was in 1927 See more words from the same year ...
A. The x-coordinate is 0 and the y-coordinate is any number. B. The y-coordinate is 0 and the x-coordinate is any number. C. Both the x-coordinate and y-coordinate are 0. D. The x-coordinate is 1 and the y-coordinate is 0. ...

is on the x-axis, and AC=5, the coordinate of point C is . 相关知识点: 试题来源: 解析 (−1,0) or (9,0) If point C is on the left side of point A, and AC=5, so the x-coordinate of point C is 4−5=−1, the coordinate of point C is (−1,0); If point ...
In the coordinate plane, the point (2, 3) is reflected across the x-axis. The new coordinate is: A. (2, -3) B. (-2, 3) C. (-2, -3) D. (3, 2) 相关知识点: 试题来源: 解析 A。本题考查坐标平面中关于 x 轴的对称点坐标特征。关于 x 轴的对称点,横坐标不变,纵坐标变为...
In a coordinate system, the point (2, -3) is reflected across the x-axis. The new point is: A. (2, 3) B. (-2, -3) C. (-2, 3) D. (3, 2) 相关知识点: 试题来源: 解析 A。当一个点关于 x 轴反射时,其纵坐标变为相反数,横坐标不变。所以点 (2, -3) 关于 x 轴反射后...
