College Algebra / Unit 6 Alg 304 short lesson, about 20 seconds
Slope as a Rate
Captions available
The idea
In a linear model, the slope is a rate — output units per input unit — and the initial value is the output at zero.
In practice
f(x) = 10x + 50 in gallons and minutes says 10 gallons per minute from a 50-gallon start.
Where people slip
A slope without its units is half a fact.
