To answer these questions, we need to analyze the graph and use the equation given. Let's go step by step:
a) The y-intercept represents the base price of $ for airfare from NYC.
To find the y-intercept on the graph, look for where the line intersects the y-axis. The y-axis represents the y-coordinate or vertical value. The value at the y-intercept will give us the base price. Find the point on the graph where the line crosses the y-axis and insert the value in the response.
b) The slope represents a cost of cents per mile traveled.
The slope represents the rate of change between the y-coordinates and x-coordinates on the graph. It tells us how the cost changes for each mile traveled. Look at the steepness of the line on the graph. If it is steep, the slope will be larger, indicating a higher cost per mile. If it is less steep, the slope will be smaller, indicating a lower cost per mile. Determine the value of the slope by observing the graph and insert the value in the response.
c) According to the equation given, someone who traveled 2,000 miles from NYC would pay $ for their airfare.
The equation given can be used to find the cost of airfare for a given number of miles traveled. Replace the variable in the equation with the given value of 2,000 miles and solve for the cost. Insert the calculated cost in the response.
d) According to the equation given, someone who paid $500 for airfare from NYC would have traveled miles.
Again, we can use the equation given to find the number of miles traveled for a given cost of airfare. Replace the variable in the equation with the given value of $500 and solve for the number of miles. Insert the calculated value in the response.
e) If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be .
To determine the new equation, replace the base price in the original equation with the new value of $50 while keeping the cost per mile the same. Write down the updated equation with the new values and insert it in the response.
By following these steps, you can answer the questions and explain how to find the solutions using the given graph and equation.
