Astudent 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?

M=(y2-y1)/(x2-x1)  so if we take the endpoints (0,0) and (6,8)

m=(8-0)/(6-0)

m=8/6

m=4/3, and since we know we have the point (0,0) we know the line is just:

y=mx, using m found above...

y=4x/3

So the graph that will match this line is one that has a point on the origin and has a positive slope of 4/3.  So another point other than the origin that will be quite clear is the point (3, 4)

It’s 24.6 after you round to the nearest tenths the answer should be 25.0

2xy/9 is the answer to this problem
