# How do you solve y<=9x-5?

May 21, 2015

I'm not sure what to solve for here; all you can do is find x in terms of y. So let's try that.

$y \le 9 x - 5$

$y + 5 \le 9 x$

$\frac{y + 5}{9} \le x$

Hmm... I guess that's not what they meant. Let's try graphing it. For this, all you have to do is graph the line $y = 9 x - 5$, and then shade in everything below that line, since y is specified to be everything less than or equal to (on or below) the line $y = 9 x - 5$.
graph{y <= 9x-5 [-39.47, 40.53, -20, 20]}
This might be a better solution to give.
