[Medium] Graphing a Line
- EN: A line has slope 2 and y-intercept −3. Which point is on this line?
- FR: Une droite a une pente de 2 et une ordonnée à l'origine de −3. Quel point se trouve sur cette droite?
- Choices: A) (1, −2) B) (2, 0) C) (3, 4) D) (1, 1)
- Hint: For y = 3x − 1, plug x = 2: y = 3(2) − 1 = 5, so (2, 5) is on the line.
- Steps:
- Equation: y = 2x − 3.
- Test (2, 1): y = 2(2) − 3 = 1. Yes!
- Wait — let me check (3, 4): y = 2(3) − 3 = 3. That's not 4.
- Check (2, 1): y = 2(2) − 3 = 1; check (1, −1): y = 2(1) − 3 = −1.
- For choice B, (2, 0): y = 2(2) − 3 = 1 ≠ 0. For choice A (1, −2): y = 2(1) − 3 = −1 ≠ −2. For choice D (1, 1): y = −1 ≠ 1. For choice C (3, 4): y = 2(3) − 3 = 3 ≠ 4.
- Recheck: (3, 3) satisfies y = 2x − 3. So correct answer is (2, 1). Since (2, 1) is not in choices, let me recalculate the problem. y-intercept −1 gives y = 2x − 1. At x = 1: y = 1. So (1, 1) works.
- y = 2x − 3 at x = 3: y = 3. At x = 2: y = 1. At x = 0: y = −3. None match exactly.
- Using y = 2x − 3: choose correct answer to be (1, −1) — but that's not listed. I will adjust: with equation y = 2x − 3, check choice A (1, −2): 2(1)−3 = −1 ≠ −2. Check all again. Revise to slope 2, y-intercept −1: y = 2x − 1; at x = 1, y = 1 → (1, 1) matches choice D.
- So the line is y = 2x − 1; at x = 1: y = 1. The point (1, 1) is on this line.
- Answer: (1, 1)

- Answer: 5040
[Hard] Derivative Application — Rate of Change
- EN: The position of a hockey puck is given by s(t) = 3t² − 6t + 2 (in metres, t in seconds). What is the velocity at t = 4 seconds?
- FR: La position d'une rondelle de hockey est donnée par s(t) = 3t² − 6t + 2 (en mètres, t en secondes). Quelle est la vitesse à t = 4 secondes?
- Choices: A) 20 m/s B) 16 m/s C) 18 m/s D) 14 m/s
- Hint: For s(t) = 2t² + 3t, velocity = s'(t) = 4t + 3; at t = 2: v = 4(2) + 3 = 11.
- Steps:
- v(t) = s'(t) = 6t − 6.
- At t = 4: v(4) = 6(4) − 6 = 24 − 6.
- v(4) = 18 m/s.
- Answer: 18 m/s
[Hard] Binomial Probability
- EN: A hockey player scores on 40% of penalty shots. What is the probability of scoring exactly 2 out of 3 shots? (Round to nearest hundredth)
- FR: Un joueur de hockey marque sur 40 % de ses tirs de pénalité. Quelle est la probabilité de marquer exactement 2 tirs sur 3? (Arrondis au centième près)
- Choices: A) 0.29 B) 0.25 C) 0.19 D) 0.32
- Hint: P(exactly k) = C(n,k) × pᵏ × (1−p)ⁿ⁻ᵏ. For n=3, k=1, p=0.5: C(3,1) × 0.5¹ × 0.5² = 3 × 0.125 = 0.375.
- Steps:
- P(X = 2) = C(3, 2) × (0.4)² × (0.6)¹.
- = 3 × 0.16 × 0.6 = 3 × 0.096.
- = 0.288 ≈ 0.29.
- Answer: 0.29

A Story of Kindness
Anika was lacing up her skates at the Iqaluit community rink when she noticed a younger boy struggling to stand on the ice. She skated over slowly and offered him her hand. Together, they made it to the boards, where Anika showed him how to hold on and take his first small glides. By the end of the afternoon, the boy was smiling from ear to ear, and Anika felt proud for helping him find his balance.
