Interpreting Slope Intercept Graphs

What is the equation that represents this situation?

The graph shows Ashley riding her bike to Maria's house. 
What was occurring from point B to point C?

• She was increasing her speed.

• She stopped for 4 minutes

• She was decreasing in speed

Edward drove 80 miles from his home to London.

He stopped and visited his friend Nicola on the way. Here is the distance-time graph for the journey.

How far was Edward from home when he visited Nicola?

• 30 miles

• 40 miles

• 10 miles

• 45 miles

What is the x- intercept of the line?

• x = 1

• y =-1

• x = -1

• y = -2

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)

This graph shows the amount of gas, in ounces, in a lawn mower gas tank, modeled as a function of time.

• The maximum amount of gas in the gas tank was 60 ounces.

• The amount of gas in the gas tank is at a maximum at 0 minutes.

• The gas tank will be empty after 60 minutes.

Edward drove 80 miles from his home to London.
