(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A line passes through (3,4). What is the maximum value of x+y?

2. Relevant equations

y = mx + b

3. The attempt at a solution

So I set up a system of equations, m3+b =4; b = Y; mX + b = 0. Then I plugged my values for X and Y into m3+b = 4..

The weird thing is though... there is no maximum value of x+y?? It's just a line, x or y could go out further and further to infinity

How should I solve this? Thanks
