Given:

The inequality is


y\leq 3x+2

To find:

The ordered pair that is NOT a solution to the inequality in the graph.

Solution:

We have,


y\leq 3x+2

Checking the inequality for (0,0), we get


0\leq 3(0)+2


0\leq 2

So, the equality is true for (0,0). it means (0,0) is a solution of given inequality.

Checking the inequality for (-2,-4), we get


-4\leq 3(-2)+2


-4\leq -6+2


-4\leq -4

So, the equality is true for (-2,-4). It means (-2,4) is a solution of given inequality.

Checking the inequality for (0,2), we get


2\leq 3(0)+2


2\leq 2

So, the equality is true for (0,2). It means (0,2) is a solution of given inequality.

Checking the inequality for (-3,4), we get


4\leq 3(-3)+2


4\leq -9+2


4\leq -7

This statement is not true. So, the equality is false for (-3,4). It means (-3,4) is not a solution of given inequality.

Therefore, the correct option is D.
