Determine whether the graph represents a proportional relationship. A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 17. Four points are shown on the graph on ordered pairs 0, 4 and 2, 8 and 3, 12 and 4, 16. These points are joined by a line. The label on the x-axis is Number of boats. The title on the y-axis is Number of passengers. Yes, it is a proportional relationship because the graph goes through the origin No, it is not a proportional relationship because the graph does not go through the origin Yes, it is a proportional relationship because the graph is a straight line No, it is not a proportional relationship because the graph is not a straight line
@mathmate
proportional relationships always pass through the origin. |dw:1431959385305:dw| Another test is if you divide the corresponding x and y values, they give the same ratios. Example: Proportional relationship: (1,2),(2,4),(3,6),(4,8)... Use (2,4) and (4,8) y/x=4/2 = 8/4 so proportional This should work for ANY pair of points.
So its A @mathmate
Does your graph pass through the origin?|dw:1431959742696:dw|
Yyes
Did you give me the point (0,4)? (0,4) is not origin, (0,0) is!
Yes
To avoid confusion, when you give your suggested answer, do not say A, B or any other letter. Please copy and paste the answer, this way you will confirm it mentally while we are communicating. Can you give me your suggested answer again?
Its answer choices
@mathmate
Yes, it is a proportional relationship because the graph goes through the origin No, it is not a proportional relationship because the graph does not go through the origin Yes, it is a proportional relationship because the graph is a straight line No, it is not a proportional relationship because the graph is not a straight line
Select you attempt and post it in words to confirm your choice, please. IF you suggest C is the choice, do not say C, but say "yes, it is a proportional relationship because the graph is a straight line" So what is your answer (not choice)
