Out of each of the equations which is a linear function A) y=x^2

B) y=3x+5

C) y=-9x

D) y=x^2-9

Option B and options C are the linear functions.

Step-by-step explanation:

The general form of a linear function is ax + by + c = 0, where a, b, and c are any real constant and x and y are the variables.

Now, from the options, we have to choose the linear function equations.

Here, option B and options C are the linear functions.

As the equation in option B and that in option C are y = 3x + 5 and y = - 9x are similar to the above general form. (Answer)
