A coordinate plane is a two-dimensional system used to describe the position of points in space. It consists of two axes that intersect at a common point called the origin. The horizontal axis (x-axis) runs from left to right across the page and the vertical axis (y-axis) runs from ...
If a point is on the x-axis and 4 units away from the origin, what is its coordinate? A. (4, 0) B. (-4, 0) C. (0, 4) D. (0, -4) 相关知识点: 试题来源: 解析 A或 B。解析:在 x 轴上且距离原点 4 个单位的点,可能在正半轴为(4, 0),也可能在负半轴为(-4, 0)。
What is the new coordinate? A. (3, 2) B. (-3, -2) C. (-3, 2) D. (2, -3) 相关知识点: 试题来源: 解析 A。解析:当一个点关于 x 轴反射时,其纵坐标变为相反数。原坐标为(3, -2),反射后的纵坐标为 2,横坐标不变,所以新坐标是(3, 2)。反馈 收藏 ...
This point is on the x-axis. Its y-coordinate is 0. What is the point? A. (1,1) B. (0,1) C. (1,0) D. (0,0) 相关知识点: 试题来源: 解析 C。A 选项两个坐标都不是 0,不在 x 轴上;B 选项 y 坐标是 1 不是 0;C 选项 y 坐标是 0,在 x 轴上;D 选项是原点,x ...
There's no such thing.A set of x, y, and z axes (the plural of axis) make up a cartesian coordinate system in 3-dimensional space, though.Check related link if you would like to see an example of x y z axis
If a point (1, -2) is reflected over the y-axis, what is the new coordinate? A. (-1, -2) B. (-1, 2) C. (1, 2) D. (1, -2) 相关知识点: 试题来源: 解析 A。关于 y 轴对称,纵坐标不变,横坐标变为原来的相反数。所以新坐标是(-1,-2)。反馈 收藏 ...
The shape is reflected across the x-axis. What happens to the coordinates? A. The x-coordinate remains the same and the y-coordinate changes sign. B. The y-coordinate remains the same and the x-coordinate changes sign. C. Both x and y coordinates change sign. D. Neither x nor y ...
Definition/Summary In Euclidean coordinate geometry, a Line usually means the whole (infinitely long) Line. (In ordinary Euclidean geometry, a Line...
Axis An unlimited line, half-line, or line segment serving to orient a space or a geometric object, especially a line about which the object is symmetric. Axes Variant of axe. Axis A reference line from which distances or angles are measured in a coordinate system. Axes Plural of axis. ...
concepts in functions is the concept of the graph, which is a visual representation of the relationship between the inputs and outputs. The graph of a function is plotted on a coordinate system, with the input values represented on the x-axis a...
