x-axis: tells about labels on x-axis, which is generally time. Show Answer. Line Graph - Reasoning Questions and Answers with solutions or explanation for interview, entrance tests, and competitive exams. There is some debate about the degree of measurement between time points. The line graph indicates changes in plotted variables with respect to the two indices calibrated on the X and the Y axes respectively. Line graphs are useful in that they show data variables and trends clearly and help us make predictions about the results of data not yet included. A line chart or line plot or line graph or curve chart is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. Line graphs can be used when you are plotting data that have peaks (ups) and troughs (downs). Line Graphs Line Graph : a graph that shows information that is connected in some way (such as change over time) You are learning facts about dogs, and … In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L that represents the adjacencies between edges of G. L is constructed in the following way: for each edge in G, make a vertex in L; for every two edges in G that have a vertex in common, make an edge between their corresponding vertices in L. The name line graph comes from a paper by Harary & … Other Forms. The x-axis is also called the independent axis because its values do not depend on anything. Match the definitions (a–f) with the vocabulary (1–6). Test Tip. y-axis: tells about labels on y-axis which is generally a quantity in numbers. In the Insert tab in SmartDraw, click on Graph and choose Line Graph.. The result is that the line of the graph always progresses in a horizontal fashion and each x value only has one y value (the company cannot have two amounts of money at the same time). A line graph is a type of chart used to show information that changes over time. Another popular form is the Point-Slope Equation of a Straight Line. Explanation. Refer to the graph & answer the questions based on line graph as given below. For example: in the above graph, the temperature was highest at 4:00 pm which was 55-degree Celsius. Children start looking at line graphs in Years 4 and 5. Then look at the graph and examine the values of the points situated in the lines of the graph. Read More. The points are connected by a line. Data points are plotted and connected by a line in a "dot-to-dot" fashion. Line graphs (or line charts) are best when you want to show how the value of something changes over time, or compare how several things change over time relative to each other. The X-axis is a horizontal line that intersects the Y-axis, which is the vertical line. Another name for a line graph is a line chart. A line graph (also known as line chart) is a graphical presentation of data that changes over time. For example, a finance department may plot the change in the amount of cash the company has on hand over time. A line graph is a type of chart used to show information that changes over time. A line graph is usually used to show the change of information over a period of time. We also call it a line chart. Useful introductory expressions: The graph shows / indicates / depicts / illustrates From the graph it is clear It can be seen from the graph As can be seen from the graph, As is shown / illustrated by the graph, The line graph consists of a horizontal x-axis and a vertical y-axis. The Complete K-5 Math Learning Program Built for Your Child. Afterward, with the help of the already given data, point out the exact values on the graph. It is a basic type of chart common in many fields. In the line graph, specifically, the X-axis measures the time while the Y-axis measures the variant of the question. Do the preparation task first. Each of these line graphs shows a change in data over time. They have an x-axis (horizontal) and y-axis (vertical).
