The diffrential equation is $\"\"$ .

(1).Draw the coordinate plane.

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

Graph :

$\"\"$

Observe the graph :

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

Explanation :

$\"\"$ on the line $\"\"$ .

Direction field $\"\"$ satisfies this condition.

Notice that on the line $\"\"$ we have $\"\"$ which satisfies the graph $\"\"$ .

$\"\"$

The correct choice is $\"\"$ .
