RS Aggarwal Solutions for Class 8 Chapter 23 Line Graph and Linear Graphs. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically. A linear graph is when this connection of points gives us a straight line. A linear graph is a model of a straight line on the X and Y-axis. It represents the equation y=mx+b.
Line graph: It is a type of graph which displays the continuous data that is changing over some time. It displays the series of data points connected with the line segments joined consecutively.
Linear graph: It is a straight line graph drawn on a plane which connects points on x and y-axis. It shows the linear relationship between the two variables.
As the Chapter is about Line Graphs and Linear Graphs, here we learn how to plot the graph, draw the line graph and read the details from the Line Graph and further solve the same.
