Determine the General and Particular solutions of this First Order Differential equation by direct integration or by separating the variables as appropriate
y^2 dx/dy= x + 1 given that when y=-1, x=1


Multiply both sides by dy



Divide every term by y²(x+1)





Now we integrate every term









We solve for y:







That's the general solution.

Now we substitute: y=-1, x=1 to find which particular 
solution is the equation for a graph of a curve that
goes through the point (1,-1)



We solve for C









We substitute that value for C in the general solution:
