Question

positive slope
zero slope
undefined slope
negative slope

Explanation:

Step1: Identify line type

The skier's path is a horizontal line, $y=-2$.

Step2: Calculate slope

Slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$. For points $(x_1,-2)$ and $(x_2,-2)$:
$m=\frac{-2-(-2)}{x_2-x_1}=\frac{0}{x_2-x_1}=0$

Answer:

Zero Slope
