✏️ Part 2: Short Answers & Graphing

5. Draw a quick sketch of y = (1/2)x. Plot and label the points (0,0), (2,1), (4,2).

6. Explain why the table x: 1, 2, 3, 4 and y: 2, 4, 6, 8 is proportional. Use the term "unit rate" in your answer.

7. Find the constant of proportionality for a line through (0,0) and (3,9). Show your calculation.

8. If y = 3x, what is y when x = 5? Show your work.

📝 Reflection & Supports

I can... identify proportional relationships from tables, equations, and graphs; find the constant of proportionality; and solve real-world proportional problems with correct units.

Success criteria: Use the term "unit rate," show calculations or a labeled graph, and include units (e.g., $ and miles) in answers.

Differentiation strategies: Printed coordinate grid available; sentence starter: "The unit rate is ___ because ___."; calculators allowed for arithmetic if needed.

Extension activities: Compare two proportional relationships by their constants of proportionality and explain which grows faster; model a real-life scenario with a table, equation, and graph (for example, cost per pound).

Dyslexia-friendly options: High-contrast, sans-serif printouts and one-step directions; highlight key terms like proportional, unit rate, constant.
