LINE GRAPH
A line graph is a diagram that shows a line
joining several points, or a line that shows the
relationship between the points.
A line graph can be taken as x-y plane, where
there will be an independent variable and a
dependent variable and it specifies how the
two variables are related to each other and
vary with respect to one another.
Mostly, the independent variable is taken on
the x-axis while the dependent variable on the
y-axis 0%

PARTS OF LINE GRAPH
 Title
The title of the graph tells us what the graph is all about.
Labels
The horizontal label across the bottom and the vertical
label along the side tells us what kinds of data is being
shown.
Scales
The horizontal scale across the bottom and the vertical
scale along the side tell us how much or how many.
Points
The points or dots on the graph represents the x, y
coordinates or ordered pairs.
Lines
The line segments connecting the points give estimated
values between the points
7
MAKE A LINE GRAPH
Steps to make a line graph:
1.Use the data from the table to choose an
appropriate scale.
2.Draw and label the scale on the vertical and
horizontal axis.
3.List the each item and locate the points on
the graph.
4.Connect the points with line segments
8
EXAMPLE:
Day Mon Tues Wed Thurs Fri
Earnings 300 450 200 400 650
Q. The table shows the daily earnings of a store for five days.
a) Construct a line graph for the frequency table.
b) On which days were the earnings above $ 400.
Solution:
a)
b) The earnings were above $ 400 on Tuesday and Friday.

Labels
The horizontal label across the bottom and the
vertical label along the side tells us what kinds of
data is being shown.
Scales
The horizontal scale across the bottom and the
vertical scale along the side tell us how much or
how many.
Bars
Represents the data amount for each group
showing comparison between among categories.
11
HOW TO CREATE BAR GRAPH?
Steps in construction of bar graphs:
 On a graph, draw two lines perpendicular to each
other, intersecting at 0.
 The horizontal line is x-axis and vertical line is y-axis.
 Along the horizontal axis, choose the uniform width
of bars and uniform gap between the bars and write
the names of the data items whose values are to be
marked.
 Along the vertical axis, choose a suitable scale in
order to determine the heights of the bars for the
given values. (Frequency is taken along y-axis).
 Calculate the heights of the bars according to the
scale chosen and draw the bars.

EXAMPLE:
Let us observe the following data of the bar
graph.
The following data gives the information of the
