垂直的数轴叫做y轴(y-axis)或纵轴,水平的数轴叫做x轴(x-axis)或横轴,x轴y轴统称为坐标轴。在同一个平面上互相垂直且有公共原点的两条数轴构成平面直角坐标系,简称直角坐标系(Rectangular Coordinates)。 资料拓展: 直角坐标系:在平面内画两条互相垂直,并且有公共原点的数轴。其中横轴为X轴,纵轴为Y轴。这样我们...
In coordinate geometry, being able to identify the coordinates of a point shown on a graph is just as important as being able to plot points. To identify the x-coordinate of a point on a graph, read the number on the x-axis directly above or below the point. To identify the y-coordi...
Q 1. Draw a coordinate system and place the coordinates (1,2), (0,4), and (-1,-3) on it. Are all of the points on a line? Can you name the line? Q 2. State true or false. On the y-axis, the x coordinate is nonzero and the y coordinate is zero.Ans:False ...
Figure 5: Find the Coordinates. Point A: (-5, 5) Point B: (1, 0) Point C: (-1, -5) Point D: (4, -3) The Y-Intercept When a point has an x-value of zero, the point lies on the y-axis. This point is called the y-intercept. For functions that model real-world...
y— y-coordinates scalar | vector y-coordinates, specified as a scalar or a vector containing numeric, categorical, datetime, or duration values. The data type of y must match the data type of the y-axis. Example: yline(10) displays a line at y=10. Example: yline([13 20 33]) dis...
axis on 显现坐标轴 (1) 坐标轴的范围(Domain of coordinates axis): 二维图形坐标轴范围在缺省状态下是根据数据的大小自动设置的,如欲改变,可利用axis(xmin xmax ymin ymax),函数来定义。 例: Q0=[680 640 620 600 630 650 670 720 760 800 740 720 700 730 760 780 740 760 790 800 850 750 730...
(42, -10) - the y-coordinate is -10 On a graph the vertical axis (the line going up and down) is the y-axis. The y-coordinates tell where a point lies on the y-axis. On this graph, Point A is graphed at the coordinate pair (0, 5): The point 0, 5 on a graphLesson...
The coordinates x,y, and z are called the relative coordinates. 坐标x, y和z叫做相对坐标. 辞典例句 The function n ( x,y) is known as the refractive index profile. 函数n ( x, y ) 称为折射率分布. 辞典例句 The heterozygoteY/ymay be distinguished by the nectary color. ...
在同一个平面上互相垂直且有公共原点的两条数轴构成平面直角坐标系，简称直角坐标系（Rectangular Coordinates）。通常，两条数轴分别置于水平位置与垂直位置，取向右与向上的方向分别为两条数轴的正方向。水平的数轴叫做x轴（x-axis）或横轴，垂直的数轴叫做y轴（y-axis）或纵轴，x轴y轴统称为坐标轴，它们的公共原点...
