Finding Constant

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, indicating how much one quantity changes in relation to another.

Front

What makes a graph proportional?

Back

A graph is proportional if it is a straight line that passes through the origin.

Front

What does a unit rate represent?

Back

A unit rate represents the amount of one quantity per one unit of another quantity.

Front

When comparing quantities, how do we express the comparison?

Back

We express the comparison as y over x.

Front

What is the rate of change in the equation y=8x+6?

Back

The rate of change is 8.

Front

Define proportional relationship.

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

What is the slope of a line in a graph?

Back

The slope of a line represents the rate of change of the dependent variable with respect to the independent variable.

Front

How do you find the constant of proportionality from a table of values?

Back

Divide the value of the dependent variable by the value of the independent variable for any pair of corresponding values.

Front

What does it mean if a graph does not pass through the origin?

Back

If a graph does not pass through the origin, it indicates that the relationship is not proportional.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for slope is (y2 - y1) / (x2 - x1).
