Is y= -7x linear or non linear

I think Linear but i am not sure

Step-by-step explanation:

A linear function is a function with standard form y = mx + b, where m is the slope and b is the y-intercept, and whose graph looks like a straight line. There are other functions whose graph is not a straight line. These functions are known as nonlinear functions and they come in many different forms.

i think is g(1)=-1.
