Which of the following is NOT a correct interpretation of a slope of -2?

For every increase of 1 unit in the y-coordinate, the x-coordinate decreases by 2 units.

For every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 2 units.

As the independent variable, x increases, the dependent variable, y decreases.

As the independent variable, x increases by 4, the dependent variable, y decreases by 8.
