In order to have a linear equation, you have to write an equation like
The sequence has to start with 3, so we must choose 
, because this guarantees that when 
we have
Now, 
must be even. In fact, if is even, 
will always be even for every possible 
, and 
will be odd.
So, for example, you might choose
Which will produce the following sequence:
and so on
Answer:
I think it's $59.37
because there are five friends and there is 5% taken away form what they really payed so you would do,

A, since the graph shows that 1 hour = 30 klm per hour. I would also label the gtaph
The students error is that they flipped where the x and y should be. so instead of x=4y it should be y=4x. or, the students error is that they forget to make it a fraction. so, it could also be x=1/4y. an equation that models this relationship is y=4x or x=1/4y
