-------------
You NEVER graph an ineqality directly. You graph the boundary of the
inequalit which is always an EQUALITY.
----
Solve your INEQUALITY for "y":
y < (-1/2)x - 12.5
---------------------------
Now, graph y = (-1/2)x-12.5 as a dashed line.

------------------------------
Then, since you want y to be LESS THAN (-1/2)x-12.5,
shade the half-plane BELOW the dashed line.
---------------------------------------

---------------------------------------
That half-plane is the graph of the INEQUALITY.

x+2y<-25
2y<-(x+25)
y<-(x+25)/2
