Remember slope is 
. In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is 
Given:
The inequality is
To find:
The ordered pair that is NOT a solution to the inequality in the graph.
Solution:
We have,
Checking the inequality for (0,0), we get
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
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
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
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.
