The distance between the points (1, 2) and (4, 6) in the coordinate plane is: A. 5 B. 6 C. 7 D. 8 相关知识点: 试题来源: 解析 A。本题涉及两点间距离公式。两点间距离公式为:√[(x₂ - x₁)² + (y₂ - y₁)²] ,代入坐标可得:√[(4 - 1)² + (6 - 2...
A. The x-coordinate is negative and the y-coordinate is negative. B. The x-coordinate is positive and the y-coordinate is negative. C. The x-coordinate is positive and the y-coordinate is positive. D. The x-coordinate is 0 and the y-coordinate is negative. ...
The coordinate plane is a plane determined by two perpendicular lines, the x-axis and the y-axis. The x-axis is the horizontal axis, and the y-axis is the vertical axis. Every point in the plane can be stated by a pair of coordinates that express the location of the point in terms...
its y-coordinate is negative.The Quadrants The coordinate plane is divided into four quadrants. Each quadrant is a specific region in the coordinate plane. The region in which x > 0 and y > 0 is Quadrant I. The region in which x < 0 and y > 0 is Quadrant II. The regio...
and its point is (0, 0).As you can see from the figure, each of the points on the coordinate plane is expressed by a pair of coordinates: (x, y). The first coordinate in a coordinate pair is called the x-coordinate. The x-coordinate is the point’s location along...

解析 A。长方形的四个顶点坐标分别为(1,1)、(1,3)、(3,1)、(3,3)。两点间的水平距离或垂直距离可以通过对应坐标相减得到。这里计算长方形的长或宽,比如水平方向上两点(1,1)和(3,1),横坐标之差为 3 - 1 = 2,所以长方形的一条边长为 2。
The horizontal axis in the coordinate plane is called the x−axisx−axis. The vertical axis is called the y−axisy−axis. The point at which the two axes intersect is called the origin. The origin is at 00 on the x−axisx−axis and 00 on the y−axisy−axis....
解析 A。解析:在平面直角坐标系中,横坐标为正,纵坐标为正的点在第一象限,点(2, 3)的横坐标 2 是正数,纵坐标 3 也是正数,所以在第一象限。选项 B 第二象限的点横坐标为负,纵坐标为正;选项 C 第三象限的点横坐标为负,纵坐标为负;选项 D 第四象限的点横坐标为正,纵坐标为负。
