For anyone out there who has this same question, the answer isn't A. y = x^3 +1 that's all I have to say

Well a line is $\sf{y=mx+b}$

So using that, can you figure out which answer is correct?

Extrinix · Answer

I’ll give a hint: $\sf{+b}$ is optional

y = one over five x ?

Does it fit into the $\sf{y=mx+b}$ equation?
