Constant of Proportionality and Slope

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, often represented in the equation y = kx.

What does a positive slope indicate about a graph?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate about a graph?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What does a slope of 0 indicate about a graph?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

What does an undefined slope indicate about a graph?

Back

An undefined slope indicates a vertical line, where x remains constant while y changes.
