For example, Grand Rapids, MI is only a 444 mile round trip that costs more than a round trip to Orlando, FL which is more miles, 1,642, and only $471 compared to the price of $548.60 for Grand Rapids, MI. We think that there should be a linear relationship between airfare and costs, because shorter distances shouldn’t cost the same or more than longer distance flights. megansmith1307 https://padlet.com/rlteusch/445y9nkmasnh/wish/164733250 2017-04-04 20:09:22 UTC https://padlet.com/rlteusch/445y9nkmasnh/wish/164733250 4. Slope= The slope is 0.0343 which is what happens to the y value when x is increased by 1. Y-intercept= The y-intercept is 470.9 and is the value when x=0 also considered the starting value. megansmith1307 https://padlet.com/rlteusch/445y9nkmasnh/wish/164733795 2017-04-04 20:12:14 UTC https://padlet.com/rlteusch/445y9nkmasnh/wish/164733795 Names rlteusch https://padlet.com/rlteusch/445y9nkmasnh/wish/164737319 Ashley Stecovich

This line fits the data in a moderately positive correlation pattern, because it is between r= 0.3 and r= 0. megansmith1307 https://padlet.com/rlteusch/445y9nkmasnh/wish/164737746 2017-04-04 20:34:13 UTC https://padlet.com/rlteusch/445y9nkmasnh/wish/164737746 7.y= 0.0343(1600) + 470.9= 525.78It should approximately cost $525.78 to fly 1600 miles. megansmith1307 https://padlet.com/rlteusch/445y9nkmasnh/wish/164737973 2017-04-04 20:35:35 UTC https://padlet.com/rlteusch/445y9nkmasnh/wish/164737973 https://padlet.com/rlteusch/445y9nkmasnh/wish/164738432 2017-04-04 20:38:09 UTC https://padlet.com/rlteusch/445y9nkmasnh/wish/164738432
