How can you determine if a table of values represents a proportional relationship?

Back

If the ratio of y to x is constant for all pairs of values, it is proportional.

Front

What characteristics define a proportional graph?

Back

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

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

Back

5

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio to each other.

Front

How can you identify a proportional relationship from a set of graphs?

Back

Look for graphs that are straight lines passing through the origin.

Front

What is the relationship between the constant of proportionality and the slope of a line in a proportional relationship?

Back

The constant of proportionality is equal to the slope of the line.

Front

If a table shows the values (2, 6), (4, 12), and (6, 18), is this table proportional?

Back

Yes, because the ratio of y to x is constant (3).
