15/20 are French so 5/20 are English
Simplified that’s 1/4
Only applies if all the books are either English or French
I think

A bottle of water cost $1.50 explain how you would make a graph of four ordered pairs to model the total cost of the water in te

oksano4ka [1.4K]

Answer:

The graph in the attached figure

see the explanation

Step-by-step explanation:

Let

x -----> the number of bottles

y ----> the total cost of the water

we know that

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

This problem represent a direct (proportional) variation

For x=1, y=$1.50

$k=y/x$ -----> $k=1.50/1=1.50$

The linear equation is equal to

$y=1.50x$

<u><em>Find the ordered pairs</em></u>

First

(1,1.50)

Second

For x=2

Find the value of y

Substitute in the equation

y=1.50(2)=3

The point is (2,3.00)

Third

For x=3

Find the value of y

Substitute in the equation

y=1.50(3)=4.50

The point is (3,4.50)

Fourth

For x=4

Find the value of y

Substitute in the equation

y=1.50(4)=6.00

The point is (4,6.00)

The four ordered pairs are

(1,1.50), (2,3.00),(3,4.50) and (4,6.00)

using a graphing tool

plot the points
