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

Back

A table represents a proportional relationship if the ratios of the corresponding values are constant and if it passes through the origin (0,0).

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

If the cost of 1 pound of potatoes is $3.50, what is the cost of p pounds?

Back

The cost c can be modeled by the equation c = 3.5p.

What does it mean if a table is not proportional?

Back

A table is not proportional if the ratios of the corresponding values are not constant or if it does not pass through the origin.
