In Algebra 1, Math Number line is the process of representing number on line based on the number ie ascending or descending the position of number will be decided based on that we can place the numbers on number line.A number line is a line in which real numberscan be placed, according to their value.Points on a number line corresponds to a real number, and every real number has each different point that corresponds to it which are called coordinates. The zero point is called the origin. Numbers which are rightside of the origin are positive numbers and numbers which are leftsideof the origin are negative numbers.The number line is a line labeled with the integers in increasing order from left to right, that extends in both directions. It contains all real number. But below in the figure only from -10 to 10 integers are uniformly labeled:
On the number line positive numbers lie on the right side of zero and negative number lie on the left side of zero.
Representation of a Number Line
Types
Decimal on a numberline
Decimal number is a number which always uses 10 as its base and it is most widely used to solve the complex problems. It is denoted with a dot (.) in between it. Decimal numbers do not necessarily contain a decimal point; 563, 5.63, and -563 are all decimal numbers.
Example:
Take the number 0 and 1 and make it into 10 parts such that we can represent it as
0.0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0
And its number line is determined as:
The hundredths place in any decimal number lies immediately after tenths place; hundredths place can be determined by making 100 parts between any two consequent numbers.
The Number Line Problems
1) Write the scale from -2 to 2?
Given:Representing scale from -2 to 2
0,0+1=1,0+2=2
0,0-1=-1,-1-1=-2
2) Represent the number scale from 10 to 100?
Given: Number scale from 10 to 100.
