Answer: y+ 7 = 5x

Explanation:

A linear function is a function in which the highest power of the unknown is 1 , that is , the highest power of the variables that are unknown will be 1.

From the question given:

A : 1 -
3x^(2) = -y

The power of x is 2 , though the power of y is 1 but because of the existence of the power of x which is 2 , it is not linear

B : y + 7 = 5x

both the power of x and y is 1 , so it is a linear function

C:
x^(3) + 4 = y is not linear

D is also not linear

likewise , E is not linear

Therefore , B is the only linear function
