Linear Patterns and Relationships

The athlete weighed 200 lbs and then started to gain 2 lbs per week.

In what ways could you model this linear pattern/relationship? Check all that apply.

• graph

• table

• equation

The plant was already 3 inches tall and grew 1.5 inches per day.

Which equation correctly models this relationship, if H = plant height and d = days?

• H = 3 + 1.5

• H = 3 + 1.5d

• H = 3d + 1.5

• H = 3 + 1.5

What is the slope of the graph shown?

• $\frac{2}{6}\ or\ 0.333$

• $\frac{4}{9}\ or\ 0.444$

• $\frac{3}{2}\ or\ 1.5$

• $0$

The graph shows the time and distance from home of a student walking to the mall from a friend's house.  

At what distance from home was the student at the beginning of the walk?

•  $3\ miles$ 

•  $4\ miles$ 

•  $6\ miles$ 

•  $9\ miles$ 

At what rate are the number of hearts increasing?

• 1 per day

• 4 per day

• 4.5 per day

• 5 per day

If the same pattern continues, how many hearts would there be at Day 3?

• 12 hearts

• 13 hearts

• 14 hearts

• 15 hearts

Which equation could be used to predict the number of hearts for future days? (x = number of days, y = total hearts)

• y = 4x + 1

• y = 4x

• y = 14x + 1

• y = 4 + 1

Look at the table to answer the question below:

The beginning amount for the total charge of this cell phone is $17.50.

• TRUE

• FALSE

Look at the table to answer the question below:

Why is $17.50 NOT the beginning charge for this cell phone?

• The beginning amount is not $17.50 because the beginning amount would be the total charge at 0 minutes.

• The beginning amount actually IS $17.50 because that's the first number in the table.

• The beginning amount would be $0.00 because all things cost $0.00 at the beginning.

• The beginning amount is 20, not $17.50.

The rate/speed of situation is the same as its __________.

• slope

• y-intercept

• starting amount

• equation
