# Graph

## Definition of Graph

Statistics: A graph is a picture that represents data in an organized manner

Algebra: A graph is a line or curve drawn on a number line or coordinate plane by joining the points represented by certain ordered pairs

• It's a pictorial representation of the data
• Graph is the best tool to understand the data in an easy way
• A graph is drawn in a grid
• A graph is drawn between X and Y axes, where X axis is a horizontal line while Y axis is a vertical line

### Examples of Graph

The figure shown below is an example of a statistical graph, called the bar graph that shows the number of people visited a park in different years.

### Solved Example on Graph

• A. Graph 2
• B. Graph 3
• C. Graph 1
• D. Graph 4

#### Solution:

• Step 1: The equation of the line with slope - 3 and y-intercept 6 is y = - 3x + 6 which is 3x + y - 6 = 0
• Step 2: So, The graph for the equation is Graph 1.

• A. Graph 1
• B. Graph 3
• C. Graph 4
• D. Graph 2
