f(x) = 3x - 1 is the linear function for the line represented by the point-slope equation
Solution:
Given point slope equation is:

We have to find the linear function for the line
The formula y = mx + b is said to be a linear function
Rearrange the given equation

Let y = f(x)
Then we get,
f(x) = 3x - 1
Thus the linear function is found
