Rs Aggarwal 2018 Solutions for Class 8 Math Chapter 23 Line Graphs And Linear Graphs are provided here with simple step-by-step explanations. In our class, however, we’ll mainly deal with constant acceleration. Once graphed, the entire class has the exact same distance versus time graph. Adjacent graph shows the uniform motion of an object. The graph of x = a is a straight line parallel to the y-axis. Distance – Time Graph: When an object is moving with uniform velocity, the slope of graph is always a straight line. If we note the distance travelled by the object at equal intervals of time (like every second or every minute), we will get a clearer picture of its speed at different points of time. Exercises to draw line graphs and double line graphs with a suitable scale; labeling the axes; giving a title for the graph and more are included in these worksheets.
