Introduction to Graphs notes: key concepts (Class 8 Mathematics)
This chapter covers reading and drawing different graphs and plotting points on the Cartesian plane, including linear graphs.
- Types of graphs
- Bar graphs, pie charts, histograms and line graphs each suit different kinds of data.
- Cartesian plane
- Two perpendicular axes (x and y) meeting at the origin; a point is located by coordinates (x, y).
- Plotting points
- Move x units along the x-axis, then y units parallel to the y-axis to mark (x, y).
- Linear graph
- A graph that is a straight line; it represents a relationship of constant rate between two quantities.
- Reading graphs
- Graphs are used to read off values and interpret real situations like distance–time or quantity–cost.
