Question

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

Answer 1

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 <= 9x - 5`

`y +5 <= 9x`

`(y+5)/9 <= 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 = 9x - 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 = 9x - 5`.
graph{y <= 9x-5 [-39.47, 40.53, -20, 20]}
This might be a better solution to give.
