Calculate f(0) and y = 0

Explanation:

Let's start with interception point with the x axis. Here we know that y = 0, so we can put that in our original expression:

4x + 0 = 8
4x = 8
x = 2

The function intercepts the x axis at (2, 0)

Let's continue with the y axis. Here we know that x = 0, so let's put that into our expression / function:

4*0 + y = 8
y = 8

This gives us interception point with y axis at: (0, 8)
