Need alot of help please

a) linear

b) nonlinear

c) nonlinear

d) nonlinear

Step-by-step explanation:

For a linear equation the highest degree is 1. If the degree is more than 1, then it is a non-linear equation.

a) 7x=y-4 is a linear equation because the highest degree is one

b)

is not a linear equation because when we multiply through by x, we get

The degree is 2

c) 6xy +3x=2 is non linear because the degree is 2.

d) x=2y³ +y is non-linear be because the degree is 3.
