# How do you graph the inequality #–3x – 4y<=12#?

##### 1 Answer

To graph this kind of inequality, the best thing is to manipulate them and obtain a relation of the form

In fact, we know that

Let's do those manipulations: starting from

adding

Subtracting 12 at both sides, we have

Dividing both sides by

which can of course be read as

We thus have

Here's the graph: graph{-3x-4y \le 12 [-10, 10, -5, 5]}
