Question

zero slope
positive slope
undefined slope
negative slope
(graph from mathbits.com with a line and a cartoon skier, four options for slope type)

Explanation:

Step1: Recall slope direction rules

A line with positive slope rises from left to right, negative slope falls from left to right, zero slope is horizontal, undefined slope is vertical.

Step2: Analyze the graph

The line falls as x increases (left to right). Calculate slope using two points, e.g., $(0,0)$ and $(1,-2)$:
$\text{slope} = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 0}{1 - 0} = -2$

Answer:

Negative Slope
