The diffrential equation is : $\"\"$ .

(1).Draw the coordinate plane.

(2).Graph the diffrential equation $\"\"$ .

Graph : \ \

$\"\"$ \ \

Observe the graph : \ \

The diffrential equation $\"\"$ represents the graph $\"\"$ . \ \

Explination : \ \

The slopes at each point are independent at $\"\"$ ,so the slopes are same along each line parallel to the $\"\"$ -axis.

Therefore graph $\"\"$ is the direction of this equation. \ \

$\"\"$

The correct choice is $\"\"$ .
