Question

Determine if the graph shows a proportional relationship.

graph of a line from 0 comma 0 going through 80 comma 12

No, it is not proportional because the line does not intersect with the origin.
No, it is not proportional because the points do not make a straight line.
Yes, it is proportional because the line intersects with the origin.
Yes, it is proportional because the axes are numbered correctly.

Answer 1

Option 3 , Yes, it is proportional because the line intersects with the origin.

Explanation:

I took the exam and I got it right

Answer 2

Option 3 , Yes, it is proportional because the line intersects with the origin.

Explanation:

A proportional relationship, when graphed will create a straight line that goes through the point (0,0); also known as the origin.
Looking at the given figure, the line is both straight and intersects the origin, making it a proportional relationship.

Knowing that the line is proportional we can eliminate the first two answers.

The third answer says "Yes, it is proportional because the line intersects with the origin." This answer is most likely the answer because a proportional relationship must intersect the origin

The last answer says "Yes, it is proportional because the axes are numbered correctly." The axis being numbered correctly does not determine whether a relationship is proportional or not.

Therefore the answer is the third one
