Robert recorded the number of miles he had biked every hour of a 4-hour bike trip. He graphed the results on the grid below. Which statement BEST explains whether or not Robert’s graph represents a proportional relationship?
A.
The graph represents a proportional relationship because the rate of miles per hour is the same at each point.
B.
The graph does not represent a proportional relationship because it is not a horizontal line showing the same number of miles traveled each hour.
C.
The graph does not represent a proportional relationship because the rate of miles per hour is always increasing.
D.
The graph represents a proportional relationship because the rate of miles per hour is always decreasing.

english, cause i can’t you

i need a diagram

step-by-step explanation:

no

i dont know the answer but here's a picture of a dog

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
