Question

Help Please I dont know ​

Answer 1

`y=2x`

Explanation:

Here we are given that for every 2 cups of water , Jada is mixing up 4 cups of Apple Juice. Hence it makes a patter which look like this as given under in a tabular format

x y

2 4

6 12

10 20

We are required to find the equation of the relation that exit between this pattern. Assuming them to be the coordinates , we will apply the two point form and find the equation.

Two point form is

`(y-y_1)/(x-x_1)=(y_2-y_1)/(x_2-x_1)` -----------------(A)

Where

`(x_1,y_1)=(2,4)`

`(x_2,y_2)=(6,12)`

Putting these values in A and solving

`(y-4)/(x-2)=(12-4)/(6-2)`

`(y-4)/(x-2)=(8)/(4)`

`(y-4)/(x-2)=2`

`y-4=2(x-2)`

`y-4=2x-4`

adding 4 on both sides

`y=2x`
