Exploring Linear and Nonlinear Functions

Luis and Kate want to play two video games for a total of 45 minutes. They use variables x and y to represent the time spent on each game, Super Bologna Man and You Have to Cut the Wire, respectively. The relationship between these times is expressed as x + y = 45. The video explores whether this relationship can be represented as a linear equation, ultimately showing that it can be written in the form y = -x + 45, confirming it is linear.

What is the total amount of time Luis and Kate plan to spend playing both video games?

• 30 minutes

• 90 minutes

• 45 minutes

• 60 minutes
