determine if there is a proportional relationship between the two quantities. explain your reasoning.
1) a b
35 92
23 80
2) c d
20 8
12.5 5
- the answer for 1) a and b is a and b are not proportional. the ratios of the values of a to b are not equal.
- the answer for 2) c and d are proportional. the ratios of the values of c to d are equal.
just explain how to know how to determine its proportional and not proportional.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

the answer is d

hope this

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

i know the point slope is y= 1/11x-46/11
