Question

A student took a test which had 6 questions. He would score 8 points on the test if all his answers are correct. If y represents the student's score when he got x questions incorrect, which graph best represents this situation? (1 point)

A. graph of line going through ordered pairs 0, 8 and 6, 0
B. graph of line going through ordered pairs negative 6, 0 and 0, 8
C. graph of line going through ordered pairs 0, negative 6 and 8, 0
D. graph of line going through ordered pairs 0, 6 and 8, 0

Answer 1

Answer: Chart A best represents this situation: Pairs (0,8) and (6,0).

Step-by-step explanation: If y represents the students score and x represents the number of questions that the student has answered incorrectly, then if the student has answered 0 questions incorrectly, they should have the highest possible score. This would mean that at no mistakes (x=0), the student would have the maximum score (y=8). This would create the ordered pair (0,8).

Following that logic, if the student has made a mistake on every single question (x=6), then they would have the lowest possible score (y=0). This would then make the ordered pair (6,0). Hope this helps!
