Below are sample questions representative of the exercises included on this worksheet and related ALG1.5 Proportional Relationships skill assessments:

Problem 1Difficulty: Mastery
Use the graph shown. Which statement correctly identifies the proportional relationship?
ALine A only is proportional, with k = 2.5.
BLine B only is proportional, with k = 2.5.
CBoth lines are proportional because both are straight.
DNeither line is proportional because both include decimals.
Solution & Explanation:Line A passes through the origin and (4,10), so k = 10/4 = 2.5. Line B has y-intercept 2, so it is not proportional.
Problem 2Difficulty: Mastery
A proportional relationship contains the point (0.8,18.4). What is y when x = 3.5?
Solution & Explanation:First find k = 18.4/0.8 = 23. Then y = 23(3.5) = 80.5.
Problem 3Difficulty: Mastery
The phrase 'y is 150% of x' describes a proportional relationship. Which equation represents it?
Ay = 0.15x
By = 1.5x
Cy = x + 150
Dy = 150x
Solution & Explanation:Convert 150% to 1.5. If y is 150% of x, then y = 1.5x.
