Answer:
The number of tickets and cost have a proportional relationship.
Step-by-step explanation:
The points on the graph would be (2,36) , (5,90) , (9,162)
Graph the lines to see if the 'lines' are straight or not.
36/2 = 18
90/5 = 18
162/9 = 18
You can just this to check, as you can see, the rate of change stayed the same, so it is linear and proportional (straight line). Constant of proportionality means that between any 2 points on a line, they will have the same rate of change (aka. slope).

I don't want to confused anyone so I'll use this chance to explain the difference between linear and proportional.
In simple terms, proportional relationships has the y-intercept at 0. So proportional lines cross the origin (0,0) while linear lines just has to be a straight.

One way is just multiplying it vertically like
754
x 4
---------
3016
Or multiply it by place value like
700 x 4 = 2800
50 x 4 = 200
4 x 4 = 16
Then add all the answers together
Answer:
Step-by-step explanation:
The given expression for water bottles is
.
The highest common factor of all the terms of this expression is 
.
We now factor to obtain;
Hence the the factorization that represents the number of water bottles and the weight of each bottle is the one in option B.
The correct answer is B
We therefore factor to obtain,
