Comparing Linear Functions in Word Problems

The video tutorial explains a wall climbing race between Nick and Alyssa. Alyssa's height is given by a linear equation, while Nick's height is analyzed using a table and backward calculation. The tutorial derives Nick's height equation and compares their starting positions, concluding that Alyssa started higher. The video demonstrates how to use linear equations and tables to analyze and compare constant speed scenarios.

What is the equation for Alyssa's height on the wall?

• a = 1/2 t + 5
