Oh hello again, I'll skip the explanation of how to find the slope since I explained with a long paragraph on your other question. But simply again, rise/run.
Now we know this is going to be a negative slope because the line is going down from left to right. So you're counting down/left.
(-4,3) to (1,-2)
I counted 5 down and 5 left. So the slope if 5/5, or just 1...

BUT NO! It's a negative slope remember? So just put a negative sign before the slope. So the slope is -5/5 or -1.
Hope this helped!
If you're going to post more questions about slope, try it yourself first and put your answer down, have us check it! See if you understand it now!
