Step-by-step explanation:
Use formula to find the slope/gradient

(-5, -1) = (x1, y1)
(5, 11) = (x2, y2)
So,

I think it’s International Classification of Diseases but I’m not sure cause it doesn’t match anything with math good luck though.
The answer is: 18 .

Answer:
4a²+3ab-a+a²
Step-by-step explanation:
So let's start off by simplifying this expression:
3a²-2ab+3b²-a+a²+5ab-3b²
Now let's subtract common terms XD
4a²+3ab-a+a²
