The coordinate of a point is (-5, 0), then it lies on: A. x-axis B. y-axis C. Quadran
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。
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 ...
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)。
If a point is on the x-axis, its y-coordinate is: A. B. 1 C. -1 D. any number 相关知识点: 试题来源: 解析 A。在 x 轴上的点,其纵坐标为 0。选项 B、C 是特定的数值,不符合在 x 轴上点的特征;选项 D 任何数不符合,只有 0 才满足在 x 轴上点的纵坐标特点。
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. ...
coordinate - a number that identifies a position relative to an axis co-ordinate Cartesian coordinate - one of the coordinates in a system of coordinates that locates a point on a plane or in space by its distance from two lines or three planes respectively; the two lines or the intersection...
As point P is the midpoint of ¯¯¯¯¯¯¯¯AB, and A (a−1,1), B (7,a), the coordinate of midpoint can be expressed as P(a+62,a+12), Because point P is on the x-axis, a+12=0,a=−1, Thus, a−1=−2, the coordinate of point A is (−2,1...
Figure 1. An x‐y coordinate graph. Each point on a plane is located by a unique ordered pair of numbers called the coordinates. Some coordinates are noted in Figure 2. Figure 2. Graphing or plotting coordinates. Notice that on the x‐axis numbers to the right of 0 are positive and ...
1In the coordinate plane, point A (−2,1) and point B (m,n) are on the same straight line parallel to the x-axis. The distance between point B and the y-axis is 3, so the coordinate of point B is . 2【题目】In the coordinate plane, point A (-2,1) and pointB(m,n) ...
