To accurately respond to the questions, I need to interpret the provided information in the graph. However, since there is no visual graph attached or descriptive data offered, I will provide placeholders or standard interpretations based on common scenarios related to airfare pricing.
You can replace the placeholders with actual values as per the graph you have.
a) The y-intercept represents the base price of $[base price] for airfare from NYC.
b) The slope represents a cost of [slope in cents/mile] cents per mile traveled.
c) According to the equation given, someone who traveled 2,000 miles from NYC would pay $[calculated cost for 2000 miles] for their airfare.
d) According to the equation given, someone who paid $500 for airfare from NYC would have traveled [calculated miles for $500] miles.
e) If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be [new equation based on the changes].
Once you identify the specific numbers from the graph, you can input them into the corresponding response areas.
