What is the gradient of the blue line?

I though gradient was something weird but its just slope. That is easy its -3.

Step-by-step explanation:

I chose two points on the line specifically ones like -2,2 because it is in the cross and makes it easier. Then I chose another one that was the next on that also was in the cross like -1,-1. The I calculated the distance by how many squares down it was and it was -3. Also I didn't have to do all that just for the explanation. Because I can just tell by looking at it.
