Question 5: A linear graph shows y increases by 4 for each unit increase in x, and y = 3 when x = 0. What is y when x = 5?
- 20
- 22
- 23 (Correct answer)
- 25
Correct answer: 23
y = 4x + 3; when x = 5: y = 4(5) + 3 = 23.
Question 6: A container holds 3.6 litres of juice. How many 250 mL cups can be completely filled?
- 12
- 13
