There really is no other way that I can think of other than guessing and checking. 3^3 is 27, when subtracted from 155 gives you 128. 128 can be rewritten as 2^7, leaving your final answer as 3^3 +2^7.

Let's say that x is the number of days he tweets. Now, if he tweets any number of days, we can represent all of that with just x. So out expression will look like:
Y=Mx+b M=3 Now you need b, so plug the x-coordinate and y-coordinate into the x and y in the equation to find the b. -5=3(-3)+b -5=-9+b Add 9 to both sides to isolate the b -5=-9+b +9. +9 4=b So the equation is Y=3x+4
