Answer:
iv ; xy + x/y = 3
Step-by-step explanation:
A non linear equation is one in which there is no product of two different variables or the same variable
What this mean is that we have the highest polynomial power as 1 or we simply have polynomials of degree 1
Looking at the given options, we can see the product xy
What this mean is that the polynomial is of degree 2 and that makes the equation a non linear as we have a polynomial of more than 1 degree
Step-by-step explanation:

The answer is 6 because you add the 1 and the 2 first and then multiple to get 6. I don’t know why you put the division sign in front of the 2 though.
(0,-1)(1,0)(2,3)(3,8)(4,15)
