Answer:

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)#
