Option D:
(0,3) is the solution to the inequalities.

Step-by-step explanation:

From the given graph, we can see that the equation of the inequalities are


$y>-x+1$ and
$y\leq 2 x+3$

To determine the coordinate that satisfies the inequality, let us substitute the coordinates in both of the inequalities
$y>-x+1$ and
$y<2 x+3$

Thus, we have,

Option A:
(1,-1)

Substituting the coordinates in
$y>-x+1$ and
$y\leq 2 x+3$, we get,


y>-x+1\implies-1>0 is not true.


$y\leq 2 x+3 \implies -1\leq 5 is true.

Since, only one equation satisfies the condition, the coordinate
(1,-1) is not a solution.

Hence, Option A is not the correct answer.

Option B:
(-4,0)

Substituting the coordinates in
$y>-x+1$ and
$y\leq 2 x+3$, we get,


y>-x+1\implies0>5 is not true.


$y\leq 2 x+3 \implies 0\leq -5 is not true.

Since, both the equations does not satisfy the condition, the coordinate
(-4,0) is not a solution.

Hence, Option B is not the correct answer.

Option C:
(3,-2)

Substituting the coordinates in
$y>-x+1$ and
$y\leq 2 x+3$, we get,


y>-x+1\implies-2>-2 is not true.


$y\leq 2 x+3 \implies -2\leq 9 is true.

Since, only one equation satisfies the condition, the coordinate
(3,-2) is not a solution.

Hence, Option C is not the correct answer.

Option D:
(0,3)

Substituting the coordinates in
$y>-x+1$ and
$y\leq 2 x+3$, we get,


y>-x+1\implies3>1 is true.


$y\leq 2 x+3 \implies 3\leq 3 is true.

Since, both equation satisfies the condition, the coordinate
(0,3) is a solution.

Hence, Option D is the correct answer.
