Question

identify the slopes of the line as positive, negative, zero, or undefined. 3. undefined zero negative positive

Explanation:

Step1: Recall slope concept

The slope of a line is given by $m=\frac{y_2 - y_1}{x_2 - x_1}$. A positive - slope line rises from left to right, a negative - slope line falls from left to right, a zero - slope line is horizontal, and an undefined slope line is vertical.

Step2: Analyze the line on the grid

By looking at the line on the grid, as we move from left to right along the line, the $y$ - values increase while the $x$ - values also increase. This indicates that the ratio $\frac{\Delta y}{\Delta x}>0$.

Answer:

Positive
