Constant of Proportionality

Front

What is the constant of proportionality?

Back

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

Front

Is the relationship between x and y proportional if y = 3x?

Back

Yes, the constant of proportionality is 3.

Front

Which equation is NOT proportional: y = 2x - 3, y = 150x, or y = 1/2x?

Back

y = 2x - 3 is NOT proportional.

Front

Which tables and graphs show a proportional relationship?

Back

Look for tables and graphs where the ratio of y to x is constant.

Front

Define proportional relationship.

Back

A proportional relationship is one where two quantities maintain a constant ratio.

Front

What does it mean if a graph passes through the origin?

Back

It indicates a proportional relationship between the variables.

Front

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

Back

Choose two points on the line, calculate the ratio of y to x for those points.

Front

If y = kx, what does k represent?

Back

k represents the constant of proportionality.
