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