Which function is a linear function?

a.
1 − 3x2 = -y
b.
y + 7 = 5x
c.
x3 + 4 = y
d.
9(x2 − y) = 3
e.
y − x3 = 8

y+ 7 = 5x

Step-by-step 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  - = -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: + 4 = y is not linear

D is also not linear

likewise , E is not linear

Therefore , B is the only linear function

Yes B is a linear function!
