Answer:
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
