y = 200 + 0.30x
The y-intercept represents the base price of $ Response area for airfare from NYC. b) The slope represents a cost of Response area cents per mile traveled. c) According to the equation given, someone who traveled 2,000 miles from NYC would pay $Response area for their airfare. d) According to the equation given, someone who paid $500 for airfare from NYC would have traveled Response area miles. e) If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be Response area.
a) The y-intercept represents the base price of $200 for the response area for airfare from NYC.
b) The slope represents a cost of 30 cents per mile traveled for the response area.
c) According to the equation given, someone who traveled 2,000 miles from NYC would pay $800 for their airfare. (y = 200 + 0.30*2000 = 200 + 600 = 800)
d) According to the equation given, someone who paid $500 for airfare from NYC would have traveled 1000 miles. (500 = 200 + 0.30x, 0.30x = 500 - 200, 0.30x = 300, x = 300/0.30 = 1000)
e) If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y = 50 + 0.30x.
