3. For one week, Sierra is going to walk half as far each
day as she did the day before. On Monday, Sierra will
walk eight miles. On Tuesday, she will walk four miles.
On Wednesday, she will walk two miles, and so on.
Which best describes Sierra’s walking plan as a function
comparing the day to the distance she walked?
1. Nonlinear function because her distance
decreases by a smaller amount each day.
2. Linear function because she walks a determined
distance each day.
3. Nonlinear function because she may not walk in a
straight line.
4. Linear function because she walks at the same
speed each day.

8. Cody has a 10-minute bus ride to school. The graph
below shows the relationship between the speed of the
bus in miles per hour versus the time it takes Cody to
arrive at school.
9. Solve for x: 4(2x − 1) = 2x + 35
1. 3.9 3. 6
2. 6.5 4. 39
10. What is the next term in the input/output table?
Choose the most accurate description of Cody’s ride to
school.
1. 26 3. 8
2. 12 4. 6
1. After Cody gets
on the bus, its
speed increases.
Then it stops for a
couple of minutes
to pick up more
students. The bus
speeds up again
before picking up
more students.
The bus stops at a
stop sign and then
speeds up once
more until it picks
up one last group
of students before
it arrives at
school.
2. After Cody gets
on the bus, its
speed increases to
20 mph for a
couple of minutes.
Then it increases
to 30 mph for a
couple of minutes.
The bus then
stops to pick up
some more
students. After
again reaching a
speed of 20 mph
for a couple of
minutes, the
school bus arrives
at school.
3. After Cody gets on the
bus, it climbs a steep
hill. Then it levels off
for a couple of miles
before going up
another hill. The bus
continues driving at the
top of the hill for a
couple of minutes
before going down a
very steep hill. The bus
then immediately
climbs another steep
hill that levels off for a
couple of minutes
before going back
down a hill to arrive at
school.
4. After Cody gets on the
bus, the speed of the
bus quickly reaches 20
mph before stopping.
After the first stop, the
bus gradually speeds
up to 30 mph. Then it
stops again. The bus
then slows down to 0
mph before speeding
back up to 20 mph
right before stopping
one more time. Finally,
it arrives at school.
11. Look at each linear relation represented below.
Identify which choices show an undefined slope? Select
Yes or No for options A – D.

Yes No
B. The line represented by​ y = 2
Yes No
C.
Yes No
D. The line that connects the points (-3, 4)
and (-3, 1)
Yes No

Hint: Use the formula d = vt + at2
Answer: v = feet/second
