Review Proportional Relationships Tables, Graphs & Equaitons

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio that describes how one quantity changes in relation to another in a proportional relationship.

Front

How do you find the unit rate from a proportional relationship?

Back

The unit rate is found by dividing the total amount by the number of units, giving the amount per one unit.

Front

What does the slope of a line represent in a graph of a proportional relationship?

Back

The slope represents the rate of change between the two quantities.

Front

What is the equation of a line in slope-intercept form?

Back

The equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you determine if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratios of the corresponding values are constant.

Front

What is the formula for finding the rate of change?

Back

The rate of change is calculated as (change in y) / (change in x).

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What does a graph of a proportional relationship look like?

Back

A graph of a proportional relationship is a straight line that passes through the origin (0,0).

Front

How do you write an equation from a proportional relationship given a table?

Back

Identify the constant of proportionality and use it to write the equation in the form y = kx.
