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 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)。反馈 收藏 ...
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....
Distance in the Coordinate PlaneLearning Outcomes Use the distance formula to find the distance between two points in the plane. Use the midpoint formula to find the midpoint between two points.Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two ...
