2. If the slope of a line representing the cost of gas is 0.25, what does this slope mean in the context of gas prices?

• The cost of gas increases by $0.25 for every two units increase in the independent variable.

• The cost of gas increases by $0.25 for each unit increase in the independent variable.

• The cost of gas remains constant regardless of the independent variable.

• The cost of gas decreases by $0.25 for each unit increase in the independent variable.
