  you are taking the following test:

 
Grade: 8,    Subject: Math,    Topic: Algebra Represent relations and functions
Question 1:
The function 2y = 4x + 10 can be written as _____________.

2y = 2x + 5y = 2x + 10

y = 2x + 5y = x + 5
 
Question 2:
The equation y = 2x + 10 is equal to the equation ___________.

x = y − 5x = 0.5y − 5

x = 0.5y − 102x = 0.5y − 5
 
Question 3:
Which of the following table represents the function y = 2x − 8?


 
Question 4:
The equation 2x + 2y + 8z = 40 can be simplified as __________.

x + y + 4z = 20x + y + 4z − 10 = 0

2x + 2y + 4z = 20x + y + 2z = 20
 
Question 5:
The function 6x + 3y - 15 = 0 is equal to the function ________.

y = − 2x + 153y = − 2x + 5

y = − 2x + 10y = − 2x + 5
 
Question 6:
Which of the following table represents the function 2y = 3x + 4?


 
Question 7:
Which of the following table represents the function 5x + 4y = 0?


 
Question 8:
Which of the following function is represented by the table shown below?

y = 3x + 1y = 3x − 2

y = 5x − 1y = 2x − 1
 
Question 9:
Which of the following function is represented by the table shown below?

x = 2y + 2y = 2x + 2

x = 2y + 4x = y + 2
 
Question 10:
Which of the following function is represented by the table shown below?

2x + 2y = 82x + 2y = 9

2x + y = 9x + 2y = 9
