Barney wants to rent a tent. He has to pay a fixed base cost plus a daily rate for renting the tent. The table shows the amount
of money, y, in dollars, that Barney has to pay for renting the tent for x days:
Tent Rental
Number of days
(x) Rent (dollars)
(y)
0 3
1 8
2 13
3 18
4 23
Which equation best shows the relationship between x and y?
y = 5x + 3
y = x + 8
y = 5x + 8
y = x + 3

(05.01 MC)
The table and the graph below each show a different relationship between the same two variables, x and y:
A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 4,100 and 5,125 and 6,150 and 7,175. On the right of this table is a graph. The x-axis values are from 0 to 10 in increments of 2 for each grid line. The y-axis values on the graph are from 0 to 300 in increments of 60 for each grid line. A line passing through the ordered pairs 2, 60 and 4, 120 and 6, 180 and 8, 240 is drawn.
How much more would the value of y be on the graph than its value in the table when x = 12?
20
30
60
70
Question 7(Multiple Choice Worth 1 points)
(05.01 LC)
The graph below shows the height through which an elevator travels, y, in x seconds:
A graph is shown with x axis title as Time in seconds. The title on the y-axis is Height of Elevator Above Ground in feet. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 125 in increments of 25 for each grid line. A line is shown connecting points on ordered pair 1, 25 and 2, 50 and 3, 75 and 4, 100. The title of the graph is Rate of Ascent.
What is the rate of change for the relationship represented in the graph?
50
25
fraction 1 over 25
fraction 1 over 50
