Interpreting Slope and Y Intercept from a Graph

What is the y-intercept of the line?

•  (0,¹/₂)

• (0,1)

• (0, ^-1/2)

• (0, -1)

Give the y-intercept

• (2,0)

• (-2,0)

• (0,-2)

• there is no y-intercept

What are the x- and y -intercepts on this graph?

• (0,5), (0,5)

• (5,0), (5,0)

• (5,0), (0,5)

• (0,0), (5,0)

Anne cycles from Bristol to Salisbury.

The diagram shows the distance-time graph of her journey.

How far from Bristol is Anne at 8:00?

• 15 miles

• 20 miles

• 10 miles

• 40 miles

Find the slope

• -3/4

• 4/3

• 3/4

• -4/3

How do you calculate slope using a graph?

• rise over run

• run over rise

• look at the y intercept

• look at the x intercept

Choose which situation does not accurately describe the event that is graphed.

• As Josh drives from his destination to his house with each passing hour he has less miles to his house.

• Josh drove 160 miles to his house in 4 hours.

• As Josh drives from his house to his destination with each passing house he is farther away from his house.

• Josh started 160 miles from his house and drove 4 hours to finally arrive.

Which one of these conclusions could NOT be drawn from this graph?

• The building only has 20 floors.

• The elevator takes about 1 second a floor.

• There are 3 level below the ground floor.

• It takes zero seconds to get to the 20th floor from the 20th floor.

Which situation could match the graph?

• A five gallon bucket of water is leaking water. Each hour that passes it leaks one gallon of water and after 5 hours it has no more water.

• A five gallon bucket of water is being filled with water by a slow drip coming from the ceiling. Each hour the bucket fills with a gallon of water. After five hours the bucket is completely full.

• A five gallon tank is being filled with water from a water faucet. Each minute the tank fills with one gallon of water. After five hours the tank is filled.

• A five gallon tank is being drained with a gallon pitcher. Each minute the pitcher is filled and taken out. It takes a total of 5 minutes to completely drain the tank.

What conclusion could not be drawn from the graph?

• Every hour 300 calories are used.

• Every hour 600 calories are used.

• After 8 hours there are no calories remaining.

• There are 2400 calories at the begining.
