Consider the data shown on the graph:
The y-intercept represents the base price of $ for airfare from NYC..
The slope represents a cost of cents per mile traveled.
According to the equation given, someone who traveled 2000 miles from NYC would pay $ for their airfare
According to the equation given, someone who paid $500 for airfaire from NYC would have traveled miles.
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be
Word Bank:
30y=30+0.50x1000y=50+0.30x800200
The missing values are:
- The y-intercept represents the base price of $30 for airfare from NYC.
- The slope represents a cost of 0.50 cents per mile traveled.
- According to the equation given, someone who traveled 2000 miles from NYC would pay $1030 for their airfare. (y = 30 + 0.50(2000) = 1030)
- According to the equation given, someone who paid $500 for airfare from NYC would have traveled 1000 miles. (500 = 30 + 0.50x, x = 940/0.50 = 1000)
- If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y = 50 + 0.50x. (the y-intercept changes to 50)
