You can put this solution on YOUR website! Tell whether the slope of a line that models each situation is positive, negative, zero, or undefined. Then find the slope.
1. The cost of tickets to the amusement park
is $19.50 for 1 ticket and $78 for 4 tickets.
---
slope = (78-19.50)/(4-1) is positive.
===========================================
2. The late fee is $2 regardless of the number of days the movie is late.
slope = zero
------
3. On the trip, Jerry had his cruise control set at 60 mi/h for 4 hours.
slope = 0
----------------
4. The contract states that every day past the agreed upon completion date the project is not finished, the price is reduced by $25.
Slope = -25
================
