Question

identify the slopes of the line as positive, negative, zero, or undefined.

Explanation:

Step1: Recall slope - concept

The slope of a line is calculated as $m=\frac{y_2 - y_1}{x_2 - x_1}$. For a line that rises from left - to - right, the slope is positive.

Step2: Observe the line

The given line on the graph rises from left to right. As the $x$ - values increase, the $y$ - values also increase.

Answer:

Positive
