The Number Line and Coordinate Plane (Day 6)

Integers are counting numbers , whole number and negative numbers.

​

• Positive Integer : An integer is positive if it is greater than 0. Ex: 1,2,3...

• Negative Integer : ​An integer is negative if it is less than 0. Ex: -1,-2,-3 ...

• Zero : This number is neither negative nor positive. It is a whole number.

  Ex: -1,-2,-3,-4 0 , 1, 2 ,3,4

Some text here about the topic of discussion

As you move to the left the numbers decrease and as you move to the right the numbers increase.

As you move down the numbers decrease and as you move up the numbers increase.

A thermometer is a tool used to measure​ temperature. Thermometers have different scales. We measure in Fahrenheit.

Distance

• If two graphed points are on the same vertical or horizontal line, you can count the distance between the two points.​

• ​If two points share the same x-coordinate, find the distance between the y-coordinates.

• If two points share the same y-coordinate, find the distance between the x-coordintes. ​

• Determine which coordinate is the same (x or y) and cross it out.

• Circle the number that is different in both coordinate pairs.

• Find the absolute value of each number (write an expression) |-2| |4|

• Find the sum. |-2| +|4|

• Distance=6

• Determine which coordinate is the same (x or y) and cross it out.

• Circle the number that is different in both coordinate pairs.

• Find the absolute value of each number (write an expression) |8| |5|

• Find the difference. |8|-|5|

• Distance=3
