which graph is not proportional? the pink graph the black graph both neither
Answer
Explanation:
Step1: Recall proportional graph rule
A proportional graph (representing a direct proportion ( y = kx )) must pass through the origin ((0,0)) and be a straight line.
Step2: Analyze pink graph
The pink graph starts at ((0,0)), so it could be proportional.
Step3: Analyze black graph
The black graph starts at ((0, 2)) (not the origin), so it does not represent a proportional relationship.
Answer:
The black graph
