State
Slope-intercept form writes a line as y = mx + b, where m is the slope and b is the y-coordinate of the y-intercept.
Show
y = 2x − 1 announces itself: slope 2, y-intercept (0, −1), no plotting required.
Watch for
The b is a coordinate, not a point by itself.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
