# Thread: how to get an equation in y=mx+b form?

1. ## how to get an equation in y=mx+b form?

The equation 5x+y < 4 is not in y=mx+b form and so I subtracted y from and got 5x < y -4 is that right? How do i get it to y=mxtb form?

You can not convert an inequality into an equality by yourself.
5x+y < 4 is an inequation that represents a region whereas y=mx+b is an equation that represents a line.
Clearly you can not convert a region into a line or vice versa.

No, it's not right. You have to separate y, not 5x as you did. $5x+y < 4 \Leftrightarrow y<4-5x$. (subtracting $5x$ on each sides). So you cannot get it to the form $y=mx+b$, but instead, into the form $y which I guess is right for your exercise.
