The new coordinate is: A. (3, 4) B. (-3, -4) C. (-3, 4) D. (3, -4) 相关知识点: 试题来源: 解析 A。本题考查了点关于 x 轴的对称性质。点关于 x 轴的对称,横坐标不变,纵坐标变为相反数。原坐标为(3, -4),对称后的纵坐标为 4,所以新坐标是(3, 4)。

The x-axis indicates the horizontal direction while the y-axis indicates the vertical direction of the plane. In the coordinate plane,pointsare indicated by their positions along the x and y-axes. For example:In the coordinate plane below, point L is represented by the coordinates (–3, 1.5...
解析 答案应该是-4/5 因为他说line m是4/5,也就是纵坐标比横坐标是四比五,然后line l 是刚好在x轴反射,所以纵坐标变号,横坐标不变,所以是负四比五结果一 题目 In the xy-coordinate plane,line M is the reflection of line L about the x-axis.If the slope of line m is -4/5,what is the...
Answer to Solved On the coordinate plane the horizontal axis is | Chegg.com
A system of coordinates in which the location of a point is determined by its distance from a fixed point at the center of the coordinate space (called the pole), and by the measurement of the angle formed by a fixed line (the polar axis, corresponding to the x-axis in Cartesian coordi...
