Ok to find dy/dx of x+2y=xy we take derivative of both sides with respect to x
1+2dy/dx = x*dy/dx +y*dx/dx
1+ 2dy/dx = x*dy/dx + y* 1
2dy/dx +1 = x*dy/dx + y
2y’ + 1 = xy’ + y
2y’ + 1 - xy’ = y
2y’ -xy’ = y - 1
y’(2-x) = y - 1
so we get finally
y’= (y-1)/(2-x)
Hope this helps you understand the concept! Any questions please ask! Thank you so much!!
If you look at the graph you can tell the graph is increasing before x = -2.
From x = -2 to x = 0, it's decreasing.
Then it's increasing again from x = 0 to x = 2, then decreasing after x = 2
So answer is the last one
It is increasing before x = -2 and from x = 0 to x = 2
