Answer:
A, C, E
Step-by-step explanation:
From the table you can see that the water depth cahnges
for every
of snow (option B is false).
This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be 
Then
Subtract these two equations:
Hence,
The equation of the straight line (the graph of linear function) is 
(option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).
Answer: Choice C
scale starts at $5 and goes to $40 with a regular $5 interval
even though we don't start at 0, the difference in bar heights is not exaggerated
graph is not misleading
=================================================
Explanation:
Choice A is not true because the vertical axis starts at 5 and not 0
Choice B is the same story as choice A.
Choice D is not true because the vertical axis does not use an irregular interval. The interval or tickmark distance is $5 each time. In other words, the value goes up by 5 each time.
So far, choices A, B and D have been crossed off the list. The only thing left is choice C.
Despite the fact that the vertical axis starts at 5, instead of 0, the graph is not misleading. The heights of the bars can be compared to see that brand H is the most expensive brand. So in a sense, we can ignore the data values along the vertical axis and still be able to see that brand H is the most expensive. The other brands are close to one another in cost.
side note: the bar graph should have a zig-zag line at the very bottom of the vertical axis to indicate "we are not starting at y = 0". This is handy if you happen to start with much larger y values.
As x goes to infinity, f(x) approaches negative infinty
as x oes to negative infinity, f(x) approaches 0
C is answer
Let c represent the cost of bus fare per week
5c = $115
c = $25
The student spends $25 per week for bus fare so the rate is $25
The equation to determine the total cost for "x" number of weeks is:
y = $25x
