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 ...
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 ...
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 和 ...
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 ...
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 ...
Definition/Summary In Euclidean coordinate geometry, a Line usually means the whole (infinitely long) Line. (In ordinary Euclidean geometry, a Line...
A fixed one-dimensional figure, such as a line or arc, with an origin and orientation and such that its points are in one-to-one correspondence with a set of numbers; an axis forms part of the basis of a space or is used to position and locate data in a graph (a coordinate axis)...
Question 3: For a linear equation y = 2x + 6, find the point where the straight line meets y-axis on the graph.Answer: On y-axis, the x-coordinate of the point is 0. Therefore, we can find the intersection point of y-axis and y = 2x + 6 by simply putting the value of x ...
