Help Please I dont know ​

Answer 1

Answer:

$y=2x$

Step-by-step 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

$\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1}$              -----------------(A)

Where

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

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

Putting these values in A and solving

$\frac{y-4}{x-2}=\frac{12-4}{6-2}$

$\frac{y-4}{x-2}=\frac{8}{4}$

$\frac{y-4}{x-2}=2$

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

$y-4=2x-4$

adding 4 on both sides

$y=2x$
