Which of the following equations is non-linear?

a. x + 5y = y + 15
b. x + 15x + 30x - 15 = 10y - 15
c. 11x = 5y + 10 - x
d. 3x + 1 = -4x + 12 -2y 2

Respuesta :

D--because it has y^2 in the equation and to isolate y you have to take the square root, the graph is going to be curved rather than linear.
