Linear Functions
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A linear function is a function whose graph is a line, written f(x) = mx + b with slope m and initial value b.
Show
f(x) = 3x − 6 climbs at 3 per step from a start of −6 — the whole behavior in two numbers.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
