Ashley runs a 1 mile warm up. She then runs at a pace of 5 miles per hour. 


How far would she run after 3.5 hours? 

y=5x+1

y=5(3.5)+1

y=17.5+1

y=18.5 miles

The original linear function is y=1/2x+5.

If a new linear function is drawn as y=1/2x-2 , explain what happened to the linear function and include how much it changed.

The y-intercept changed from +5 to -2 so the linear function moved down 7 units.

A company charges $20 to deliver a package and $5 for each pound the package weighs.


If you only have $50 to ship a package, how many pounds can the package weigh?

y=5x+20

50=5x+20

30=5x

x=6 pounds
