Answer:
The answer is group C
Step-by-step explanation:
The graph of group C depicts a typical and perfect presentation of the linear equation y+3=0
Simplifying the above equation thus:

Make y subject of formula by subtracting 3 from both sides. Thus,


Therefore, we draw a straight line across -3 on y axis. Hence, group C linear graph.
