4. JaMonte is riding a portion of the Silver Comet bike trail that is 36 miles long. The graph represents JaMonte’s ride along the bike path from 3:00 to 6:00 p.m. What is JaMonte’s average speed?
a) 3 miles per hour
b) 6 miles per hour
c) 12 miles per hour
d) 36 miles per hour
9. The table below gives the number of cars, c
, that are produced at a car plant for every year, t
, since 2004.
Which equation represents this data, and what does the slope
represent in this scenario?
a) c
= 917
t
+ 18,500; the slope represents 917 cars at the plant
initially
b) c
= 417
t
+ 18,500; the slope represents 417 cars at the plant initially
c) c
= 417
t + 17,500 +; the slope represents 417 additional cars produced each year
d) c
= 917
t + 17,500; the slope represents 917 additional cars produced each year

13. During a science experiment, JaTerria is adding marbles to a glass of water. She began with a glass of water and recorded
the number of marbles added and the depth of the water in the table below.
JaTerria found that the data in the table fit the linear model d
= 35 + 0.6
m
. What is the real-world meaning of the 35?
a) The number of marbles JaTerria added to the glass.
b) The volume of each marble is 35 cubic mm.
c) Each marble increased the depth of the water by 35 mm
d) Before JaTerria added any marbles, the water was 35 mm deep
