This graph shows the relationship between what two variables? What do the x values stand for and what do the y values stand for?

Hours (x) and miles walked (y)

I go to the story and buy meat for $8.99 a pound. Is this a proportional relationship? Why or why not?

Yes it is proportional because  $8.99 per pound is a unit price. (Cost for 1 pound)

Is this table proportional? If so, what is the C.O.P? How do you know?

No, this relationship is NOT proportional. There is no constant rate of change between my x and y variables.

Is this graph proportional? Why or why not?

No, it is NOT proportional. It does not pass through (0,0) and (0,0) would not be a part of this graph. It passes through (0,1). 

Another reason: There is not constant rate of change. My y/x value for one point is 1 and 3/4 for the other point showing there is not constant rate of change.

Cassidy drove at a constant rate. It took Cassidy 2 hours to drive 100 miles. How far would she drive in 1 hour? How do you know?

Cassidy is driving at a constant rate so I can use my proportionality equation. Cassidy would drive 50 miles in one hour. I know this because y (100) divided by x (2) equals 50.

Which equations below are proportional?

y = 2x

y = 2x + 1

y = 1.5x

y = 4x - 2

y = 2x  and  y = 1.5x

13 candy bars weigh 26 ounces. What is the weight of 35 candy bars?

35 candy bars weigh 70 ounces

400

Is the equation below proportional? How do you know?

y = 3x + 2

No it is not proportional because there is a number being added to x. This causes the graphed line to not go through the origin (0, 0).

A car travels 120 miles in 3 hours (with a constant speed). How long will it take to travel 200 miles?

It will take 5 hours to travel 200 miles because my rate of change is 40 miles per hour.

500

Is the equation below proportional?

y = x


Yes, there is not anything being added or subtracted to the x so it will go through the origin.
