How to Compare Linear Functions: Equations, Tables, and Graphs
TL;DR: Comparing two linear functions boils down to checking two numbers each: slope (the rate of change) and y-intercept (the starting value). Whichever line has the steeper slope grows faster as x increases. Whichever has the higher y-intercept starts out ahead. That’s the whole comparison, and the beauty is it works no matter how each […]
