# What is the difference between a proportional and non-proportional table?

## What is the difference between a proportional and non-proportional table?

A non-proportional graph is a straight line that does not go through the origin. How to tell the difference: A proportional table has a constant of proportionality in that y divided by x always equals the same value. A non-proportional table will have different values when y is divided by x.

**What is an example of a proportional relationship table?**

The relationship between the quantities of grape juice and peach juice is a proportional relationship. In a table of a proportional relationship, there is always some number that you can multiply by the number in the first column to get the number in the second column for any row.

### What are non examples of proportional relationships?

How can you use non- proportional relationships to solve real-world problems? The distance a car can travel on a tank of gas or a full battery charge in an electric car depends on factors such as fuel capacity and the car’s efficiency. This is described by a nonproportional relationship. more than one word in each box.

**Can a table be proportional?**

First, remember that not ALL tables will display a proportional relationship. To determine if a proportional relationship exists, you need to look for equivalent (equal) ratios within the table. Hopefully your table will be relatively small, as ALL values within the table will need to be checked.

#### Where does a proportional relationship go on a graph?

PROPORTIONAL RELATIONSHIPS Will always go through the origin on a graph. (0,0) Graph will always be a straight line. Always write the constant ratio in the form of Reduce or divide to find the constant ratio for each. PROPORTIONAL OR NON-PROPORTIONAL?

**When are two quantities said to be non-proportional?**

NON-PROPORTIONAL If two quantities are proportional, then they have a constant ratio. If the ratio is not constant, the two quantities are said to be non-proportional. We will make tables and look at the relationship between the variables to determine proportionality. PROPORTIONAL RELATIONSHIPS Will always go through the origin on a graph.

## How can you tell if a ratio is proportional?

In order to tell from a table if there is a proportional relationship or not, you can check to see if the ratio is the same. The ratio is also known as the scale factor.

**Which is an example of a proportional equation?**

Write an equation to fit this situation: EXAMPLE 1 Sal’s Pizzeria sells large pizzas for $11 but charges a $2 delivery fee per order. Ashley and Megan are running around a track. They run equally fast, but Ashley started later. When Ashley has run 5 laps, Megan has run 15 laps.
