The y-coordinate that completes the point exists 5.

<h3>What is an ordered pair?</h3>

An ordered pair (x, y) denotes the x-and-y coordinates of a general point, where x exists the input value of a function and y exists the output value of a function.

The output value exists y = f(x) and must be found using the rule (function) to the given input value.

In this case the rule exists f(x) = - 3x + 2, and the input value, x, exists - 1 (the first value of the ordered pair).

This exists the mathematical procedure:

x = - 1

f(x) = f (-1)

Then substitute the value x = -1 then

f(-1) = -3 (-1) + 2 = 3 + 2 = 5.

Therefore, the correct answer is option b) 5.

Given:

Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.

To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.

To find:

The number of ounces in each container of ginger ale.

Solution:

Let n be the number of ounces in each container of ginger ale.

According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,

$\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}$

$\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}$

$5\times 18=2\times \text{Ginger}$

$90=2\times \text{Ginger}$

Divide both sides by 2.

$45=\text{Ginger}$

So, ginger required for punch is 45 ounces.

Number of containers = 3

Number of ounces in each container of ginger ale = n

Number of ounces in 3 containers of ginger ale = 3n

Now,

$3n=45$

Divide both sides by 3.

$n=15$

Therefore, 15 ounces are in each container of ginger ale.
