Lesson(s) Review Flashcard

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant ratio between two variables, often represented as k in the equation y = kx.

Front

How do you find the constant of proportionality from a graph?

Back

To find the constant of proportionality from a graph, identify the slope of the line, which represents the ratio of the change in y to the change in x.

Front

What is the formula for the constant of proportionality?

Back

The formula for the constant of proportionality is y = kx, where k is the constant.

Front

What does a slope of 1 indicate in a graph?

Back

A slope of 1 indicates that for every unit increase in x, y increases by the same amount, showing a direct proportionality.

Front

How do you express a constant of proportionality in an equation?

Back

You express a constant of proportionality in an equation as y = kx, where k is the constant.

Front

What does a constant of proportionality of 2 mean?

Back

A constant of proportionality of 2 means that for every unit increase in x, y increases by 2 units.

Front

What is the relationship between slope and constant of proportionality?

Back

The slope of a line in a graph represents the constant of proportionality between the two variables.

Front

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

Back

The constant of proportionality is 3.

Front

What does a slope of 0.5 indicate?

Back

A slope of 0.5 indicates that for every 2 units increase in x, y increases by 1 unit.
