Question

To bill customers for water usage, one city converts the number of gallons used into units. This relationship is represented by the equation u = 748g, where g is the total number of gallons of water used and u is the number of units.

Determine which statements about the relationship are true. Choose two options.

g is the dependent variable.
u is the dependent variable.
g is the independent variable.
u is the independent variable.
The two variables cannot be labeled as independent or dependent without a table of values.

Answer 1

True statements:
- u is the dependent variable.
- g is the independent variable.

Reason: u is given as a function of g (u = 748g), so u depends on g (g is the input/independent variable).
