Direction from the Slope
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 increasing when its slope is positive, decreasing when negative, and constant when the slope is zero.
Show
f(x) = 3x − 6 rises everywhere; g(x) = −x + 10 falls everywhere; h(x) = 7 stays put — one sign, one verdict.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
