For the sum we have the following properties:
The properties are commutative, asosiative, distributive and neutral element.
Commutative property: When two numbers are added, the result is the same regardless of the order of the addends.
Associative property: When three or more numbers are added, the result is the same regardless of the order in which the addends are added.
Neutral element: The sum of any number and zero is equal to the original number.
Distributive property: The sum of two numbers multiplied by a third number is equal to the sum of each summand multiplied by the third number.<span><span>
</span><span>For subtraction we have:
</span><span> The arithmetic operation of the subtraction (subtraction) is indicated by the minus sign (-) and is the opposite, or inverse, operation of the addition. </span><span>That is, it is an arithmetic operation that serves to find the difference between two numbers.

Answer:
Step-by-step explanation:

D. 3 pages are edited every 5 minutes
For a line to be parallel, the slope has to be the same(1/3) only its coordonate on the y axis (b) changes.
Therefore the new equation will be y=1/3x+b
To find be, tou have to isolate it after inputting the new coordinates (-9,4)
(4)=1/3(-9)+b
4=-3+b
7=b
Therefore, the new equation is
y=1/3x+7
If you have a graphing calculator or even a website you can graph the equation down then look at the x axis where 3 and 4 is. After you do that look at the y axis where you will find what 3 and 4 equals to then you will subtract those numbers and that should be the answer
