PPT for chapter INTRODUCTION TO GRAPH class 8th

2. INTRODUCTION..
Graph are visual representations of data
collected.
Data can also be presented in the form of
table , however a graphical presentation is
easier to understand.

3. There are various types of graphs such as:
 Bar Graph
 Pie Chart {circle graph}
 Histogram
 Line Graph and
 Linear Graph

4. So today we will learn
about Linear Graph.

5. LINEAR GRAPH..
A linear graph displays
data that changes
continuously over periods of
time

6. HERE IS THE EXAMPLE OF
LINER GRAPH.

7. {0,2},{0,5},{0,6},{0,3.5}

8. A[1,1},B{1,2},C{1,3},D{1,4}

9. {1,3},L{2,3},M{3,3},N{4,3}

10. W{2,6},X{3,5},Y{5,3},Z{6,2}

11. COORDINATES…
The graph sheet is itself a square
grid . The point lying on x axis are
known as x coordinates . And the
point lying on y axis are known as y
coordinates.
