How do I do Slope Intercept Form Step to Step? PLEASE HELP!

So if an equation was f(x)=x+4

you would automatically change f(x) into y

so it would y-y=x(x-x)

so you plug in the x and 4 which is the first y and x

y-4=x(x-x)

you switch the numbers around

so your final answer would be x-4

answer: the answer is ann

answer: its the third option.
