How do you identify a proportional relationship in a graph?

Back

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

Front

What is the equation format for a proportional relationship?

Back

The equation format for a proportional relationship is y = kx, where 'k' is the constant of proportionality.

If y = 5x, what is the constant of proportionality?

Back

The constant of proportionality is 5.

Front

What does it mean if the constant of proportionality is greater than 1?

Back

If the constant of proportionality is greater than 1, it indicates that y increases faster than x.

Front

What does it mean if the constant of proportionality is less than 1?

Back

If the constant of proportionality is less than 1, it indicates that y increases slower than x.

Front

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

Back

To find the constant of proportionality from a table, divide the y-value by the corresponding x-value for any pair of values.
