Sara graphs a line passing through points that represent a proportional relationship. which set of points could be on the line that sara graphs?

Option B). (6,8),(0,0),(18,24)

Step-by-step explanation:

The options of the question are

A). (2,4),(0,2),(3,9)

B). (6,8),(0,0),(18,24)

C). (3,6),(4,8),(9,4)

D). (1,1),(2,1),(3,3)

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Verify each case

case A) (2,4),(0,2),(3,9)

This set of points not represent a proportional relationship because in a proportional relationship the intercepts must be equal to (0,0) and this set of points have the point (0,2)

case B) (6,8),(0,0),(18,24)

Find the constant of proportionality k

For x=6, y=8 ---->

For x=18, y=24 ---->

The line passes through the origin

The linear equation is

so

This set of points could be n the line that Sara graphs

case C) (3,6),(4,8),(9,4)

Find the constant of proportionality k

For x=3, y=6 ---->

For x=4, y=8 ---->

For x=9, y=4 ---->

The values of k are different

therefore

This set of points not represent a proportional relationship

case D) (1,1),(2,1),(3,3)

Find the constant of proportionality k

For x=1, y=1 ---->

For x=2, y=1 ---->

The values of k are different

therefore

This set of points not represent a proportional relationship

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.
