Is bullet drop proportional or not? (how does gravity affect the bullet)
Bullet drop is nonproportional, it will drop faster and faster the longer it is in the air.
X: 1, 2, 3, 4
Y: 25,50,75,100
Is this proportional?
Proportional
X: 0, 1, 2, 3, 4
Y: 2, 4, 6, 8, 10

Would the relationship between the number of $5 pencils you can buy with $100 be linear? What about proportional?
The relationship is linear and proportional.
The relationship would be linear and proportional, the cost per pencil does not change and there is no added cost. When graphed, the points will also form a line, making the relationship linear.
Create a simple situation where the rise and decline of a species population can be displayed on a graph.
The population of rabbit's in a national park went up during spring, but then dropped midsummer due to a drought. (answers will vary)
Draw a graph using the equation y=1.5x+2.
sample points: (0, 2), (1, 3.5), (2, 5)

Describe this situation: Mike started riding his bike from his house to the store. He stopped to buy a bag of candy and rest a little at the store, then headed home.
A steady rise upward, then a flat area where Mike is not moving. Lastly, the graphed points should decline back down to 0 on the y axis at an angle.

Lia was walking to her friend's house, stopped at a store to buy water, then continued to the house. She stayed with her friend for a while then went back home. Make a graph of her progress.
The graph should go diagonally up for a bit, continue across without rising a little, then go up diagonally again, go flat, and finally go down to the x-axis at an angle.
do the points (2, 5), (7, 2), (-3, 4), (2, 9) and (1, 1) make a function?
They do not make a function.
X: 1, 2, 3, 4,5, 6
Y: 14,28,42,56,80,94

When tracking the population of a species on a graph, how would a sudden increase or decrease in the population be shown on the graph? How would the addition of a large group of the species being tracked affect the graph?
When tracking a population on a graph an increase in population would be shown by a steeper incline upwards and a decrease by a decline in the plotted points. The addition of a large group to the population would give the graph a steep incline.
Convert this equation into slope intercept form, then graph it. -8x+4=32

A tree has a diameter of 20 inches midway up its trunk. The diameter will increase at a rate of approximately 4/5 of an inch every year. Using the equation y=4/5x+20 draw a graph of the equation, and describe the relationship.
The relationship is linear and nonproportional. Example points on the graph would include (0,20), (10,28), (20,36),(30,44) and (50,60).
A store started carrying a new type of candy two weeks ago, but so far nobody has bought any of it. However, over the next 3 weeks there will be a steady increase of customers buying it. Using this information, draw a graph to show the candy sales over the five weeks described.
The graph should have no increase on the y-axis for the first 2 weeks, then start to steadily rise as more and more of the candy is bought over the next 3 weeks.
