Answer
The function y = 3x - 5 is a linear function.
Option (A) is correct .
Reason
Definition of linear function
Linear functions are those whose graph is a straight line.
A linear function has the following form. y = f(x) = a + bx.
A linear function has one independent variable and one dependent variable.
Thus the graph of this function y = 3x - 5 is linear as given below and it is in the form of y = f(x) = a + bx .
Here y is dependent and x is independent variable.
Therefore y = 3x - 5 is a linear function.
