Question

what is the slope in the picture? positive undefined negative zero

Explanation:

Step1: Recall the concept of slope

The slope of a line is calculated as \(m=\frac{y_2 - y_1}{x_2 - x_1}\). A positive slope means the line rises from left to right, a negative slope means it falls from left to right, a zero slope is a horizontal line, and an undefined slope is a vertical line.

Step2: Analyze the image

In the image, the surface (which can be approximated as a line) rises as we move from left to right.

Answer:

Positive
