Intersections on a Graph

Ask something about your teacher...

• Where did they grow up?

• How long have they been living in the Austin area?

• What's one thing different about math when they were a student?

• If they remember who was their 8th grade Math teacher?

What is this graph about?

• The Ribbon Sales of Frank and Erica

• How many ribbons are sold over how many days?

• Both

The x-axis measures the number of ribbons left for Frank and Erica to sell.

• TRUE

• FALSE

At the start, who has more ribbons left to sell?

• Frank has more left to sell at the start because his graph is steeper.

• Frank has more left to sell because his y-intercept is greater.

• Erica has more left to sell but she sells all of her ribbons first.

At the intersection (18, 15)...

• There are 18 ribbons left to sell and it took 15 days.

• There are 15 ribbons left to sell and it took 18 days.

Which statement is true from the graph?

• Company A has a greater initial/starting cost.

• Company B is more expensive per mile because it's graph is steeper.

• Company A is more expensive per mile because it's graph is steeper.

• Company B has the lower initial/starting cost.

If you want to rent a car at a lower price, which company should you go wtih if you plan on driving around 100 miles?

• Company A is cheaper at 100 miles because the graph is lower.

• Company B is cheaper at 100 miles because the graph is lower.

• Either company seems like a good choice since the graph is an intersection at 100 miles.

Which statement is true?

• Company A will charge $30 if you rent the car and drive about 40 miles.

• Company B will charge $30 as a starting fee.

• Both

Since there is an intersection, there be an instance where both taxis will charge the same amount.

• True

• False

On the graph, at the point of intersection

• Both taxis are charging $10

• Both taxis are charging $15

• Both taxis are charging $20

• Both taxis are charging $5
