To interpret the equation \( y = -2x - 8 \):

  1. Slope: The slope (m) is the coefficient of \( x \), which in this case is \( -2 \). This means for every 1 unit increase in \( x \), \( y \) decreases by 2 units.

  2. Y-Intercept: The y-intercept (b) is the constant term, which is \( -8 \). This means the line crosses the y-axis at \( (0, -8) \).

  3. Direction of the Line: Since the slope is negative, the line falls from left to right.

Based on this interpretation, the correct response is:

The slope is −2, the y-intercept is −8, and the line is falling from left to right.
