Graphs serve as visual representations of data, enabling quick and easy understanding, especially when showing trends or comparisons. Different types of graphs, particularly line graphs, display continuously changing data over time. The relationship between independent and dependent variables can be effectively demonstrated through these graphs, guiding insights into variations and relationships between quantities.

What we have learnt
- Graphical presentation of data is easier to understand.
- A line graph displays data that changes continuously over periods of time.
- A line graph which is a whole unbroken line is called a linear graph.
- To fix a point on the graph sheet, we need an x-coordinate and a y-coordinate.
- The relation between dependent variable and independent variable is shown through a graph.
Key Concepts
-
Term: Line Graph
Definition: A type of graph that represents data changes continuously over time by connecting points with a line.
-
Term: Independent Variable
Definition: A variable whose variation does not depend on another variable, often plotted on the x-axis.
-
Term: Dependent Variable
Definition: A variable that depends on another variable, commonly plotted on the y-axis.
-
Term: Linear Graph
Definition: A graph that forms a straight line, indicating a constant rate of change.
