The equation that represents a nonlinear equation from the given option is 2(y + x) = 0
A nonlinear equation is one where the highest degree of a variable is two or more than two.
It can be in any other form of the equation but does not form an equation of y = ax + b. It also produces a curve slope since every two points on the graph are not the same.
From the information given:
x(y-5) = 2
xy - 5y = 2
-5y = - xy + 2
5y = xy - 2
y = (xy - 2)/5
y -2(x+9)=0
y - 2x - 18 = 0
y = 2x + 18
3y + 6 ( 2-x) = 5
3y +12 - 6x = 15
3y - 6x = 15 - 12
3y -6x = 3
3y = 6x + 3
2(y + x) = 0
2y + x = 0
2y = -x
y = -1/2x
