Linear Relationships Equity Quiz

In the equation T(d) = m d + b, what does T(d) represent?

The total cost of the trip

Correct Incorrect Correct answer

The total travel time for a given distance

Correct Incorrect Correct answer

The number of buses on the route

Correct Incorrect Correct answer

The number of people riding

Correct Incorrect Correct answer

What does the slope (m) tell us in a transportation model?

The total distance traveled

Correct Incorrect Correct answer

The starting delay before departure

Correct Incorrect Correct answer

How many minutes it takes to travel each mile

Correct Incorrect Correct answer

How many stops the bus makes

Correct Incorrect Correct answer

What does the intercept (b) represent?

How far the route goes

Correct Incorrect Correct answer

How long you wait before the trip begins

Correct Incorrect Correct answer

The total number of neighborhoods

Correct Incorrect Correct answer

The time it takes to travel one mile

Correct Incorrect Correct answer

If Neighborhood A has the model T(d) = 6d + 4, what does that mean?

The bus takes 6 minutes per mile and waits 4 minutes before starting

Correct Incorrect Correct answer

The bus takes 4 minutes per mile and waits 6 minutes before starting

Correct Incorrect Correct answer

The bus route is 6 miles long

Correct Incorrect Correct answer

The total trip time is always 4 minutes

Correct Incorrect Correct answer

Which route is faster for long trips?

T = 8d + 8

Correct Incorrect Correct answer

T = 12d + 2

Correct Incorrect Correct answer

T = 6d + 10

Correct Incorrect Correct answer

T = 10d + 0

Correct Incorrect Correct answer

What does a bigger slope (m) mean?

The bus is faster

Correct Incorrect Correct answer

The bus is slower

Correct Incorrect Correct answer

The wait time is shorter

Correct Incorrect Correct answer

There is no change in time

Correct Incorrect Correct answer

If a line graph is steeper, what can we say about that neighborhood’s commute?

It has fewer bus stops

Correct Incorrect Correct answer

People get to work earlier

Correct Incorrect Correct answer

Travel time increases quickly as distance increases

Correct Incorrect Correct answer

The buses are less crowded

Correct Incorrect Correct answer

Why is it important to compare slopes and intercepts across neighborhoods?

To find which route looks nicest on a map

Correct Incorrect Correct answer

To understand which areas have slower, longer commutes

Correct Incorrect Correct answer

To know which bus has the best seats

Correct Incorrect Correct answer

To predict how many buses the city owns

Correct Incorrect Correct answer

Using your own words, explain how slope and intercept can show fairness or unfairness in public transportation.
