Two students are scrolling TikTok after school.
Student A has already watched 120 brainrot videos and keeps scrolling at 10 videos per minute.
Student B has already watched 60 brainrot videos and keeps scrolling for 14 videos per minute.
Who watched more videos after 10 minutes?
Student A - 220 videos after 10 minutes
Student B - 200 videos after 10 minutes
Student A watched more videos after 10 minutes!
600
Can a graph be nonlinear but still represent a function? Why or why not?
Yes - Think about a "V" shaped graph. This is nonlinear, but still represents a function because it passes the vertical line test (no x-values repeat).

In Fortnite, two players are running towards the safe zone.
Player A starts 200 meters away and runs at a constant speed of 5 meters per second.
Player B starts 140 meters away and runs at a constant speed of 3 meters per second.
Write a linear equation for BOTH players.
Player A: y=-5x +200
Player B: y=-3x + 140
