# Math Help - Graphing inequalities

1. ## Graphing inequalities

I have to graph the inequality y<4x but don't know how to get it into y=mx+b with 2 variables. Help?

2. your inequality $y<4x$ is already in the form of $y = mx+b$, the only difference is ,you have no equals sign. Treat the less than sign as an equals and graph the equation. Make the line dotted this implies it is either less than or greater than, then shade the required region and you are done.

3. You don't always need two variables. In your case, $b = 0$.

If this helps, you can write your inequality like this :

$y < mx + b$
$y < 4x + 0$
