Jane spent 2 hours exploring a mountain with a dirt bike. First, she rode 48 miles uphill. After she reached the peak she rode for 14 miles along the summit. While going uphill, she went 5 mph slower than when she was on the
summit. What was her rate along the summit?

i believe that the answer is

b. y-1=-2(x-4)

hope this !

step-by-step explanation:

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.
