Front

What makes a graph proportional?

Back

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

Front

What is the equation for a proportional relationship given a table of values?

Back

The equation can be determined by finding the constant of proportionality (k) and using the formula y = kx.

Front

Is the table proportional?

Back

A table is proportional if the ratio of y to x is constant for all pairs of values.

Front

What is the equation y=mx for a proportional relationship?

Back

In the equation y=mx, m represents the constant of proportionality.

Front

What does the slope of a proportional graph represent?

Back

The slope represents the constant of proportionality, which is the ratio of y to x.

Front

How can you determine if two quantities are proportional?

Back

Two quantities are proportional if their ratios are equal.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the factor by which one quantity is multiplied to obtain the other in a proportional relationship.
