## How can you use tables graphs and equations to represent proportional situations?

How can you use tables, graphs, and equations to represent proportional situations? Sample answer: If the ratio between one quantity and another is constant, you can use tables, graphs, and equations of the form y = kx to represent a proportional relationship between the quantities.

How can you represent a proportional relationship using an equation?

A proportional relationship between a quantity y and a quantity x that has a constant of proportionality k is represented by the equation y = kx. If an equation in a different form can be rewritten as above, then it is a proportional relationship.

What does it mean for an equation to be proportional?

A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if: y=kx. for some constant k , called the constant of proportionality .

### How is using a graph to represent a proportional relationship like using a table How is it different?

If you can draw a straight line through all three points and the line passes through the origin, (0, 0), the ordered pairs represent a proportional relationship. Solution The points on the graph represent a proportional relationship. Show that the ordered pairs in the table represent a proportional relationship.

What is a proportional table?

In a proportional table, the y-value divided by the x-value in that row is the same for every row (that is, the ratio y/x is constant). However, in a non-proportional table, y/x is not constant.

How can u represent a proportional relationship using an equation?

A proportional relationship between a quantity y and a quantity x that has a constant of proportionality k is represented by the equation y = kx.

## What is the equation for proportional relationships?

Proportional Relationships in Algebraic Formulas We can state this proportional relationship with the formula, y = kx. Y and x here are the quantities that are proportional to each other. The k here is called the constant of proportionality, sometimes known as the unit rate.

Which of the following is an advantage to using tables?

Tables provide fast and efficient readability across issues displayed in rows and columns. They can serve as a common means for benefit-risk communications because of their simple structure, flexibility and the ease with which they can be adapted.

What can you observe about the table and graph Is it linear?

Linear functions graph as a straight line, no curves allowed. So, if the graph is a straight line, it is the graph of a linear function. From a table, you can verify a linear function by examining the x and y values. The rate of change for y with respect to x remains constant for a linear function.
