Which of the following represent a horizontal function? select two answers.

a. 2y=2(x+y)
b. 2x−2y=2x+4
c. x=7
d. y=2
*explain your reasoning*

B and D

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c ( c is the value of the y- coordinate the line goes through )

y = 2 ← is in this form → D

and consider

2x - 2y = 2x + 4 ( subtract 2x from both sides )

- 2y = 4 ( divide both sides by - 2 )

y = - 2 ← in the form y = c → B

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:
