Parallel lines - Lines that never intersect or cross are parallel lines. This is the point (0,0) in a two-dimensional graph. Origin - The origin is the point where the X and Y axis intersect on a graph. scale is possible only for positive values (either on abscissa or ordinate). Ordinate - The vertical line, or y-axis, of a graph. Many of the Gwyddion data processing modules produce graph as an output. Number pair - Two numbers that represent a point on a graph, also called the coordinates. The coordinate of C in the adjacent graph is: 4. The coordinate of B in the adjacent graph is: 3. The coordinate of A in the adjacent graph is: 2. Noncollinear points - A set of three points that are not located on the same line. Grade 8 Maths Introduction to Graphs Multiple Choice Questions (MCQs) 1. Start your trial now First week only 4.99 arrowforward. The value corresponding to the horizontal distance of a point on a graph from the Y axis The X. Solution for Which of the following is the equation of the normal at x1 1 abscissa on the graph of the y x² + ln x function Skip to main content. Midpoint - The point of a line segment that is the same distance from both endpoints. The point (3,2) has 3 as its abscissa and 2 as its ordinate. Use the Graph Abscissa (Horizontal) Axis area on the Quantity tab to select specific locations for your graph result window display. Line segment - A portion of a line with two endpoints. The vertical axis of a graph is known as the ordinate and the horizontal axis of a graph is. Line - A straight object that is infinitely long and thin. The value of a co-ordinate on the vertical axis of a graph. Intersecting lines - Two or more lines that meet at a point are intersecting. For example, to graph the NCR data for frequency of call outs(per hour), enter the first data point in cell C7. Horizontal - A flat or level line or plane that is perpendicular to the vertical. Other names include ordered pair and numbered pair.Ĭoplanar lines - Two or more lines that are on the same plane or flat surface.ĭiameter - A line segment that passes through the center of a circle with each end point being on the circumference.Įndpoint - The point at the end of a line segment or ray. In this video, we’ll be showing you how to set the X and Y Axes in Excel.The X axis in a chart shows the category names or numbers. The first number indicates the x-axis and the second number the y-axis. The center of the Cartesian grid, the intersection point of the axes, is called the origin of the graph.Īny point in the Cartesian plane can be located by specifying its two coordinates, x and y.Example of x-axis, y-axis, and coordinates on a graphīisect - To bisect an object is to divide it into two equal halves.Ĭollinear - A set of three or more points that are lying on the same straight line are collinear.Ĭoordinates - A set of two numbers that indicate where a point is on a graph. If each axis is like a 1-dimensional number line, where x is positive on the right, negative on the left, and y is positive above the x-axis and negative below it, we have these results for each quadrant: Quadrant The two axes divide the Cartesian plane into four quadrants, which we label, beginning with the upper right and moving around counterclockwise, as Quadrants I, II, III and IV, using Roman numerals. We don't usually use "ordinate" and "abscissa" too much these days, but you should know that you might hear them. The horizontal axis is called the abscissa and is usually labeled as the x-axis. The vertical axis is called the ordinate, and is usually labeled as the y-axis. To find the values of abscissae and ordinates of various points given in a cartesian plane. (in a system of coordinates) the distance from a point to the vertical or y-axis. The Cartesian coordinate system consists of two axes (plural of axis) drawn at right angles to one-another. nounplural noun abscissae/abssi/, plural noun abscissas.
