Hey there Wcrystasia!!!!! The first thing that you need to realize is what slope-intercept form is. Remember that it is y=mx+b. I always say one variable on the left, while everything else is on the right. After you do that, you need to set up some equations. Seats Each cycle has 1 seat. You know there are 21 seats. So
u+b=21
Manipulate that equation into something that looks like slope-intercept form.
u+b=21
u+b−b=21−b
u=21−b
Now just rearrange the terms on the right side. You have an answer. If you needed the other equation, it would be set up like
u+2b=30
SO the answer is 30 !!!! HOPE I HELPED!!!!!!!!!!!
