find all points on the curve x^2y^2+xy=2 where the slope of the tangent line is -1 I know that you have to find the derivative when it equals -1 i got y'=(2x*y^2-y)/(2x^2*y+x) (i don't know if it is correct or not) but i don't know how to go from here. any

Find the interval on which the curve of y= the integral from 0 to x of 2/(1+3t+t^2)dt is concave up. Can someone please explain? I'm so confused about how to find the answer, all I know is if the 2nd derivative is positive then it's concave up.
