Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
Substitute the values and solve for k
therefore
the equation of the line is equal to

<h3>Order to solve Math Operations</h3>
When you solve any Math Operations, it is necessary to be attentive to the order of the operations.
First, you should solve the operation insides of Parentheses. After that priority is given to Exponents. Thereon, you can solve multiplication or division operations from left to right. Finally, addition or subtraction from left to right
See the order below
- Parentheses
- Exponents
- Multiplication or Division from left to right
- Addition or Subtraction from left to right
The question gives the expression (4a² +2ab) - (2a² -ab + b²). Therefore, for solving the expression you should follow the order of the math operations.
4a² +2ab -2a² +ab - b²
2a²+3ab-b²
Like, there are no more similar terms. Therefore, you can represent the expression (4a² +2ab) - (2a² -ab + b²) by the expression 2a²+3ab-b².
