Line Equation Sprint
Sixty seconds on the clock. Read slopes, write line equations, and convert forms before the timer runs out — three lives, streak bonuses, and difficulty that ramps up as you play.
1 Play
Answer with the same formats as Practice: y=2x+3, 2x-y=-3, x=-3,
or a plain number for slopes and intercepts.
How the sprint works
- 60 seconds on the clock — answer as many as you can.
- +10 points per correct answer. At a streak of 4+, every extra streak level adds +2.
- 3 lives — a wrong answer costs one heart and resets your streak.
- Difficulty ramps up: reading m and b first, then writing equations, then two-point and standard-form conversions.
Time’s up!
2 Rules & scoring
The sprint rewards speed and accuracy — a wrong answer costs a heart and kills the streak, so steady beats frantic.
Answer formats
Equations: y=2x+3. Standard form: 2x-y=-3. Vertical: x=-3.
Slopes and intercepts: plain numbers like -1/2.
Scoring
10 points per correct answer. From a streak of 4, each extra level adds +2 — so a streak-5 answer is worth 14. Best score is remembered for this session.
Difficulty ramp
0–20s: read m and b, horizontal and vertical lines. 20–40s: write equations from data. 40–60s: two points and standard-form conversions.
